Seems like my future depends on answering this question I'm completely new to Numpy can someone give me code for this question
You are rolling 5 dice at a time. When the dice come out as 1-2-3-4-5 or 2-3-4-5-6, then it is called a largest straight. Write a python program to get the count of happening largest straight when we simulates rolling five dice 10000 times.
how can I get a random generation of yes and no? and result store in dataframe column.
I want to the random generation of yes and no and store value in the column but still not successful... here is my code, it's working well but does not store the same result in the column.
import string
import random
l1 = ["yes", "no"]
for x in range(8):
rand = random.randint(0, 1)
print(l1[rand])
import random
import matplotlib.pyplot as plt
a = 5
b = 10
c = 20
x = (print(random.randrange(a, b)))
y = (print(random.randrange(b, c)))
projectname = input('What is your project name?: ')
indep = input('What is your independent variable?: ')
dep = input('What is your dependent variable?: ')
plt.plot(x, y)
plt.xlabel(indep)
plt.ylabel(dep)
plt.title(projectname)
plt.show()
Here is the error code: "ValueError: x, y, and format string must not be None"
New to coding
The code is printing the greeting and all the messages except the number. I need to see what is being generated by my random number generator.
#include <iostream>
#include <cstdlib>
#include <ctime>
void greeting(int pnum){
if(pnum == 1) {
std::cout << "Please press \"ENTER\" to roll the die";
}
else {
std::cout << "Please press \"ENTER\" to roll the die AGAIN";
}
std::cin.ignore();
}
int dieroll(void){
int ran;
srand(time(NULL));
ran = rand()%6+1;
std::cout << "You have rolled :" << std::endl;
return ran;
}
int main(void){
int counter, firstdie, ran;
char firststart;
do {
greeting(1);
firstdie = dieroll();
}
while (ran > 0);
{
return ran;
}
std::cin.ignore();
return 0;
}
I'm a beginner so i'm unsure where to start trouble shooting. I'm looking into making local variables.
I created this code 3 different ways.
Are any of these the preferred ways in how the code should be written?
Are any of these good?
Maybe one of these could be modified or adjusted.
I was told different things on how the code should be made.
How it works is, after a page is loaded, only 1 background is selected from a group of backgrounds.
Clicking Run Code snippet produces a new background image.

}I am trying to shuffle the string elements in a 2d array, and I'm quite confused whether I should just shuffle the columns or all of them. Here's what I've done so far.
int main(int argc, char const *argv[]){
char words[4][20] = {"abc", "dec", "dsz", "dfas"};
for (int i=0;i<4;i++){
srand(time(NULL));
int r = rand() % 4;
int temp = i;
strcpy(words[i], words[r]);
strcpy(words[r],words[temp]);
}
for(int j=0;j<4;j++){
printf("Elements: %s\n",words[j]);
};
return 0;
}
However, this gives me a Trace/BPT trap: 5 error. Any helps would be appreciated.
So im trying to do a luck game and i try to find something like Crash game that generate a random number with a probability like this can up to x100 but most of the time it's ~x1 - x2 and more rarely x3 - x8.
I dev in c#.
This code is to return a subset with size k from the set size n (EPI 5.15). That is, take n > 0, k <= n, and from n we (hypothetically) form a set {0, 1, 2, ..., n-1} from which we pick k elements to form a subset. There are nCk possibilities of picking a subset and we want it to be uniformly picked and we also want the permutation in that subset is also random. There are three versions of codes -- from official solution, my tweak, and my own solution. The latter two are WRONG but I don't know why. I will explain the gist of the algorithm right below the three codes.
def random_subset(n: int, k: int) -> List[int]:
H = {}
for i in range(k):
r = random.randrange(i, n)
rmap = H.get(r, r)
imap = H.get(i, i)
H[r] = imap
H[i] = rmap
return [H[i] for i in range(k)]
def random_subset(n: int, k: int) -> List[int]:
H = {}
for i in range(k):
r = random.randrange(i, n)
H[r] = H.get(i, i)
H[i] = H.get(r, r)
return [H[i] for i in range(k)]
def random_subset(n: int, k: int) -> List[int]:
H = {}
for i in range(k):
r = random.randrange(i, n)
if r in H:
H[i] = H[r], i
else:
H[i] = r, i
return [H[i] for i in range(k)]
We pick an element from the part of array A, <0, 1, 2, ..., n-1>, without duplicate. At first, pick r from array A and swap it with A[0]; then pick another r and swap it with A[1] ... until we have filled A[k-1], in total we have k elements, like the following code:
'''
A = <0, 1, 2, ..., n-1>
i 0 1 2 n-1
'''
def random_sampling(k, A):
for i in range(k):
r = random.randrange(i, len(A))
A[i], A[r] = A[r], A[i]
A = [i for i in range(n)]
k = some_constant
random_sampling(k, A)
answer = A[:k]
To reduce space complexity from O(n) to O(k) by mimicking an array <0, 1, 2, ..., n-1>, we changed the right above code into an official solution that uses a hash table from which we select an element to be included in a subset. The problem arises in the way I use hash table differently from original answer but I don't know why.
I have a function in which a random number is generated as shown below
public void method(){
int number = random();
// continue
}
My question is how can I access this variable without mocking random method?
I need this variable for my test scenarios.
I'm trying to write a code that generates a password from a string, if user wants a 8 character pass the code takes a string with 5 letters and adds randomly 3 more chars at the end and changes randomly to upper case a letter. For example:
Input: pedro
Output: pEdRo/*+ (Symbols should be generated randomly)
But I'm getting: EEpEdro-$!
Why I'm getting EE at the beginning of the vector? I have tried to use .erase but did not work, also I always got the same chars at the end (-$!) instead of random chars. Hope you can help me :)

I got an exercise while learning python from this tutorial and I got an exercise of Snake, Water and Gun and did solve it but the program just takes an input and then stops. This is the code I am using:
import random
print("Welcome to Snake, Water or Gun!")
opts = ["Snake", "Water", "Gun"]
u_ch = input("Enter Snake, Water or Gun:")
c_ch = random.choice(opts)
chances = 10
ties = 0
u_score = 0
c_score = 0
while chances < 10:
if u_ch == "Snake" and c_ch == "Snake":
chances -= 1
ties += 1
print("It is a tie.")
print(f"{chances} chances left.")
elif u_ch == "Snake" and c_ch == "Water":
chances -= 1
u_score += 1
print("Computer wins 1 point.")
print(f"{chances} chances left.")
elif u_ch == 'Snake'and c_ch == "Gun":
chances -= 1
u_score += 1
print("You win 1 point.")
print(f"{chances} chances left.")
if u_ch == "Water" and c_ch == "Snake":
chances -= 1
c_score += 1
print("Computer wins 1 point.")
print(f"{chances} chances left.")
elif c_ch == "Water":
chances -= 1
ties += 1
print("It is a tie.")
print(f"{chances} chances left.")
if c_ch == "Gun":
chances -= 1
u_score += 1
print("Player wins 1 point.")
print(f"{chances} chances left.")

print("Computer wins 1 point.")
print(f"{chances} chances left.")
elif c_ch == "Gun":
chances -= 1

print("It is a tie.")
print(f"{chances} chances left.")
if c_score > u_score:
print(f"You lose!\nComputer score:{c_score}\nYour score:{u_score}\nTies:{ties}")
if u_score > c_score:
print(f"You win!\nComputer score:{c_score}\nYour score:{u_score}\nTies:{ties}")
if c_score == u_score:
print(f"Tie!\nComputer score:{c_score}\nYour score:{u_score}\nTies:{ties}")
I am not able to understand the problem at all.

//So I am brand spanking new to javascript (like, I've been dropped into the deep end for this for my intro to engineering class with only my wits and the p5.js references), so forgive me if this question is obvious to you, because it's stumping my teammate and I.//
I am making a game where you are given a randomized phone number and you have to use some numbered buttons to type in the random number to win. We have managed to get that part to work, after a bit of head scratching, but I can't seem to figure out how to get the number to reset after someone wins the game. What we're working on right now is making the win state nicer than just a bit of text saying "you win" or "you lose" with nothing else to follow. Our plan is to have a screen pop up that gives you the option to play again or go to the home screen to choose another game to play. Since I'm the one who figured out how to get the phone number to randomize, I need to figure out how to get it to reset. If you guys could help, I'd very much appreciate it.
this is what I have for my generator so far:
let number1, number2, number3, number4, number5, number6, number7, number8, number9, number0, randNum;
function getRandomInt() {
return Math.floor(Math.random() * 10);
}
number0 = getRandomInt();
number1 = getRandomInt();
number2 = getRandomInt();
number3 = getRandomInt();
number4 = getRandomInt();
number5 = getRandomInt();
number6 = getRandomInt();
number7 = getRandomInt();
number8 = getRandomInt();
number9 = getRandomInt();
randNum = '(' + number0 + number1 + number2 + ') ' + number3 + number4 + number5 + '-' + number6 + number7 + number8 + number9;
When I had the variables to create a random number in a function, they would be randomizing constantly, and when I took them out, they were set, but now that they're outside of a function, I don't know how to get them to reset.
Given the code below, is it possible to modify it so that there's a single set of M "random" numbers for x and y that will "restart" at the beginning of the set for every iteration of i?
What I know I can do is pre-generate an array for x and y of length M but I cannot use arrays because of limited memory. I was thinking of using random numbers with seeds somehow but havent been able to figure it out.
Thank You!
double x = 0;
double y = 0;
double a = 0;

if (r == 0 || r > 1) return sampleNormal();
double c = sqrt(-2 * log(r) / r);
return u * c;
}
for(int i = 0; i < N; i++)
{
for(int j = 0; j < M; j++)
{

I want to join strings but randomly. If I do this:
a = 'this'
b = 'is'
c = 'a'
d = 'string'
e = ''
f = e.join(a + b + c + d)
output : 'this is a string'
This is excatly what I don't want.
I want to get string in random order. Like this:
'string this a is'
I'm a newbie. Consider the following. For any LOC_ID that has more than 3 unique SUB_IDs, I take a random sample of 3 unique SUB_IDs to piece together a new dataframe with concatenate:
df_concat = pd.DataFrame(columns=['LOC_ID', 'SUB_ID'])
for loc in test_df['LOC_ID'].unique():
sub_ids = test_df[test_df['LOC_ID'] == loc]['SUB_ID'].unique()
if len(sub_ids) > 3:
np.random.seed(622)
sub_ids_max = np.random.choice(sub_ids, size=3, replace=False)
df_sample = test_df[test_df['SUB_ID'].isin(sub_ids_max)]
else:
df_sample = test_df[test_df['SUB_ID'].isin(sub_ids)]
df_concat = pd.concat([df_concat, df_sample], ignore_index=True)
The following is the real case where I also have a year component with 6 years. Each LOC_ID within locids_sub has more than 10 unique SUB_IDs in at least one year. Per LOC_ID, per year, I need to ensure that there are no more than 10 unique SUB_ID's:
max_subid = 10
years = df_bb['Year'].unique()
count_df = df_bb.groupby(['LOC_ID', 'Year']).nunique().reset_index()
locids_sub = count_df[count_df['SUB_ID'] > max_subid]['LOC_ID'].unique()
# Subset df_bb by locids_sub
df_bb_sub = df_bb[df_bb['LOC_ID'].isin(locids_sub)][['Year', 'LOC_ID', 'SUB_ID']]
df_concat = pd.DataFrame(columns=df_bb.columns) # Initializing df
for year in years:
for loc in locids_sub:
sub_ids = df_bb_sub[(df_bb_sub['Year'] == year) & (df_bb_sub['LOC_ID'] == loc)]['SUB_ID'].unique()
if len(sub_ids) > max_subid:
np.random.seed(year+int(loc[-2:]))
sub_ids_max = np.random.choice(sub_ids, size=max_subid, replace=False)
df_sample = df_bb[df_bb['SUB_ID'].isin(sub_ids_max)]
else:
df_sample = df_bb[df_bb['SUB_ID'].isin(sub_ids)]
df_concat = pd.concat([df_concat, df_sample], ignore_index=True)
With 6 years, 1460 LOC_IDs in locids_sub, and 1828201 rows in df_bb, this takes 30 minutes to run.
Please let me know how to make this more efficient.
How would I generate unique 16 digit alphanumeric based on input number in python. Result should be the same if we run the function multiple times. for example if the input is 100 and the program returns 12345678abcdefgh and next time if the user provides same input it should return the same result 12345678abcdefgh.
I want to generate a random variable that follows Weibull Distribution. I have the mean and coefficient of variation (COV). I want to know how to generate it using either python or Matlab. Since the scale and shape are not given.
var cells = [
[1, 2, 3, 5],
[1, 1, 2, 3],
[1, 1, 1, 2],
[0, 1, 0, 1]
]
The challange is to pick one equally random 0 from cells and change it randomly to a 1 or 2.
The chance of it changing to a 1 should be 90%. The chance of a 2 10%.
cells will always be a 4x4 array.
I am wondering if there are some faster solutions (even if it is uglier) that I cannot find. Anything slighly faster is welcome as an answer!
Your solution should rather not use external libraries.

As in the question name I'm trying to get a random name generator but it doesn't work because i get error CS1525 on (27,8) i tried changing The Random but it doesn't work i also tried changing the name of the Random but it doesn't work i tried indenting it differently also doesn't work please help me
Note:I am not all that good at coding so some of the things i say might not make sense like changing the Random i'm not sure if that is how you say it but i don't know any other way so sorry if it's confusing.
In Clojure's rand function, the lower limit 0 is included, but the upper limit is not. How to define a rand function equivalent which includes the upper limit?
I want to do a random-effect multivariate meta regression model using the package 'meta' in r. However, when I used 'metareg' function, the output I got is the mixed effect models. How can I get the estimates from the random-effect model? I am very new to the meta analysis. Please help me.
For example I have 2 different Gaussian random number generators. The first mathematical expectation is 50 and the variance is 5. The second mathematical expectation is 60 and the variance is 5. (Actually I don't know their mathematical expectation and variance) They generate random signals at the same time. Maybe the first one produces "46 48 50 49 55 56 53 52". The second produces "60 56 59 62 66 54 59 57". I can only detect jumbled numbers right now, like "46 60", "48 56", "50 59", "49 62", "55 66", "56 54", "53 59", "52 57".
I know this problem can be easily solved by increasing the number of samples. But what I am facing now is to determine the mathematical expectation of these two different random number generators in as few samples as possible. Is there any algorithm to solve this problem, please.
So I've been trying to do this for an embarrassingly long time now. First of all here is my (very bad) code:
char firstInfection() {
char cities[] = {"aa", "bb", "cc", "dd", "ee", "ff"};
srand(time(NULL));
int randnum = rand() % 5;
char firstCity = cities[randnum];
return firstCity;
}
I didn't include the preprocessor stuff but I'm also using string, math and time (obviously stdio and stdlib too)
Line 2 errors out here, saying: error: too many initializers for ‘char []’ I'm not really sure what's going on here.
I'm having trouble understanding some of the things I need to do. I was told on tutorialspoint that I have to initialize random with line 3: srand(time(NULL)) I'm not sure why lol.
I tried shortening the names of the elements in cities[]
I'm not really sure what else to do try. I'm guessing that the whole thing is completely wrong but I really don't know.
how can i get random item something mix everytime user open the app. right now i having a gridview that show item but not randomly. i just get all of the data in firestore and show it into gridview with unlimited length of item that look like this

I would like to randomly choose 2 dates from the list of dates based on condition that if date range between 2 randomly choosen dates from the list is lower than 100 days we want to take them if not we look for other 2 random dates from the list.
Code below will not work but this is more or less what I would like to achieve:
dates = [date(2020, 1, 25), date(2020, 2, 23), date(2020, 3, 27)]
def get_2_random_dates_with_with_days_range_100():
choosen_dates = random.choice([a, b for a, b in dates if a.days - b.days <= 100])
Also code above shows more or less what I've tried which is to use list comprehension with the condition but it would require me to unpack 2 values from the list
Thanks

The title doesn't serve this question justice but I don't know how else to phrase it. (I already know that the contents of the console can be saved with a right-click, this is something different.) I'm using this for a different purpose, but let's simplify it so it's easier to understand. let's say that I have this code:
function getRandomInt(max) {
return Math.floor(Math.random() * max);
}
const numberRandom = getRandomInt(999);
console.log(numberRandom);
This basically generates a 'random' number with a max of 999, let's say I want to run this code 100 times and have the output be saved to a text file, like this: "12, 135, 765, 457, 876" etc. Would there be a quick and clean method to do that? If not, what is the next best solution?
I need to generate a random index in an array without using any library such as random. For example I have an array of size=30, I need to generate an index that is within index 0-29 randomly. Perform this using hard code only and without any library.
I wanted to know how i could insert values randomly in an array. I have 4 values to randomly put in a 4x4 array
I need to create random numbers in a user specified range. I understood how to create random numbers and refering to Generating random numbers of exponential distribution that question. However, I need my random numbers to be in a range. I wrote a piece of code, althogh it works in theory, because it calculates very little numbers it approaches 0 and give wrong numbers. My code is
double u;
double p1 = -1.0 * lambda * minvalue;
double p2 = -1.0 * lambda * maxvalue;
double a_min = 1 - exp(p1);
double a_max = 1 - exp(p2);
u = (rand() / (RAND_MAX + 1.0));
double diff = a_min - a_max;
u = u * (a_min - a_max);
u = u + a_max;
double p3 = 1.0- u;
int x = (int)(-log(p3) / lambda);
return x;
lambda, minvalue and maxvalue are all integers. How can I deal with this issue ot is there any alternative solutions?
My code deals with very little numbers and so it is rounded to 0 then the result is calculated wrongly .
Please note I am only allowed to use Math and Random class
so for this, I was considering using "for loop" for the number of of digits restriction from quantity_digit and use ''.join() function to add things up. The list might be like this ["333322","999883"].
I was wondering how do I for each iteration, randomly pick an element and within that element, pick random number from it. Can this be done? Please help
so this is I want to do
Title "Engines Generate a Sequence of Numbers" in section 17.4.1 has following Warring.
A given random-number generator always produces the same sequence of numbers. A function with a local random-number generator should make that generator (both the engine and distribution objects) static. Otherwise, the function will generate the identical sequence on each call.
"A given random-number generator always produces the same sequence of numbers." What kind of given generator does it refer to?
If I give a random number engine and a random number distribution, they form a given random number generator.
So I compiled and ran the following code on different compilers.
#include <iostream>
#include <random>
using namespace std;
minstd_rand0 dre1(13232);
minstd_rand0 dre2(13232);
int main()
{
uniform_int_distribution<unsigned> h1(0,10);
uniform_int_distribution<unsigned> h2(0,10);
unsigned t=100;
while(t--){
cout << "dre1：" << h1(dre1) << endl;
cout << "dre2：" << h2(dre2) << endl;
}
}
For it's easy to watch, I won't release all the results.
//in gcc and clang:
dre1：1
dre2：1
dre1：5
dre2：5
dre1：1
dre2：1
dre1：9
dre2：9
dre1：6
dre2：6
//in msvc
dre1：0
dre2：0
dre1：0
dre2：0
dre1：3
dre2：3
dre1：2
dre2：2
dre1：0
dre2：0
Why did this happen?
I have a dataset of about 6000 words. I'd like to pull two samples of 25 words each, however the average WordLength for both samples must be the same, and all words across both samples must be different.
This is what my data looks like:
Word Type CEFR WordLength
a indefinite article a1 1
abandon verb b2 7
ability noun b2 7
able adjective a1 4
This is just one of the criteria I need the samples to match on; if this is straightforward to you, please consider taking a look at my other question which adds a more complicated level: Scraping Oxford5000 words and obtaining two equivalent word lists
I need to display a 1 random submission from the most 100 hot reddit submissions after entering the command. This is my code without randomness, it's just send me 100 posts:
@bot.command()

title = submission.title
embed = discord.Embed(title=f'__{title}__', colour=discord.Colour.light_gray(),
timestamp=ctx.message.created_at, url=url)
embed.set_image(url=url)
await ctx.send(embed=embed)
I've tried random.choice(), but it didn't worked:
async for submission in picture_submission.search(f"{name}", params={'include_over_18': 'on'}, limit=100):
random.choice(submission)
url = submission.url
title = submission.title
embed = discord.Embed(title=f'__{title}__', colour=discord.Colour.light_gray(),
timestamp=ctx.message.created_at, url=url)
embed.set_image(url=url)
await ctx.send(embed=embed)
Error:

Before I moved from PRAW to AsyncPRAW I've used this and it worked fine:

picture_submission = reddit.subreddit("Genshin_Impact").search(f"{name}", sort="hot", params={'include_over_18': 'on'})

I am trying to have the string be randomly generated and used in a for loop.
When I try, I can’t seem to get it to even generate be a string with “n” letters.
I tried to add together multiple chars to create a string, but, from the for loop, all of the chars are the same. (I tried using chars because I will be doing a project with them and I need experience.) I have resorted to using strings and I need help finding out how to do the random generation.
I was making a python program where you type in an input, and it finds a random number from 1 to that input. It won't work for me for whatever reason.
I tried using something like this
import random
a = input('pick a number: ')
print(random.randint(1, a))
input("Press enter to exit")
but it won't work for me, because as soon as it starts to print it, cmd prompt just closes. does anyone know how to fix this?
I'm trying to make a bot that will send a random message from an array using cron.
Here is my code:
const cron = require('cron');
module.exports = {
name: 'pesanrandom',
description: "random message every day",
execute(message, args, cmd, client, Discord){
let scheduledMessage = new cron.CronJob('00 54 16 * * *', () => {
//
var listPesan = [
'Met siang guys, dah pada mam siang blum?',
'Siapa yang tadi pagi mimpiin cowo atau cewe kpopnya',
'Siang-siang enaknya...',
'Dor kaget ga',
'Laper dah',
];
var pesanRandom = listPesan[Math.floor(Math.random() * listPesan.length)];
const pesanEmbed = new Discord.MessageEmbed()
.setColor('#50C878')
.setTitle('vermillion#3039')
.setDescription(pesanRandom)
.setFooter('© Vermillion')
client.channels.cache.get('927589065925214239').send(pesanEmbed);
//
});
scheduledMessage.start()
}
}
I already try the code and it works but it can only randomize the message one time. How to make it randomize the message everytime the message is sent?
I'm trying to randomize position my div on the x axies. As default my div value is 5em (console.log(balloon.offsetWidth) => 80 in px)
get random number between 2 numbers:
function getRandomNumber(min:number, max:number){
return Math.floor(Math.random() * (max - min) + min);
}
setting random position among the body width - the width of the div to prevent overflow
function setBalloonRandomXAxies(balloon:HTMLDivElement){
balloon.style.left = `${getRandomNumber(0, (body.offsetWidth - balloon.offsetWidth))}px`
}
I'm still getting results bigger than: (body width - balloon width).
this works but, not dynamic maybe my div will change sizes sometimes
balloon.style.left = `${getRandomNumber(0, (body.offsetWidth - 80))}px`
Any helpers out there ?
I've registered a new widget area in functions.php using
'name' => __( 'Grand angle sous les articles', 'twentyten' ),

'before_widget' => '<div id="grand-angle">',

I'm calling this new widget area in a php template like this :
<?php if ( is_active_sidebar( 'grand-angle' ) ) : dynamic_sidebar( 'grand-angle' ); endif; ?>
Inside this new widget area I'm now adding several custom html widgets and I would like to display them randomly. These custom html widgets contain ads (mostly images) and I need to set up a rotation. Any idea how to do that? Thank you very much for your help.

Python newbie The purpose of the code is to add together the two digits within a random two-digit number (e.g. 11 = 1+1 = 2)
import random
def add_double_digits():
num = random.randrange(10, 99)
snum = str(num)
print(num)
print(int(snum[0]) + int(snum[1]))
add_double_digits()
I've had to create a variable called "snum" (string number) which converts the number into a string and then back again so that I can get the index of the individual digits. I hope I'm using the correct terminology. Is there a more efficient way of doing this/ am I lacking some fundamental knowledge here or is this the way it should be done? Thanks.
I have an nXn matrix (or an image) and I want to randomly break it into different continuous regions where each region has its unique color. The following specs for each region:
My initial thought is to start with point (0,0) and then randomly generate xandy such as np.random.randint(Z,M). Then, draw a line between the randomly generated x and y. However, the problem with this approach that it needs to keep track of all pixels/elements or some of them will end up not assigned to any region, which is time consuming. Anyone has a better idea?
I have the following vector in R: c(0,1).
I am wishing to randomly sample from this vector 10 elements at a time, but such that no more than 2 elements repeat.
The code I have tried is sample(c(0,1),10,replace=T)
But I would like to get
sample(c(0,1),10,replace=T) = (0,1,1,0,1,1,0,0,1,0)
sample(z,4,replace=T) = (0,1,0,1,0,0,1,0,1,0)
but not
sample(z,4,replace=T) = (1,0,0,0,1,1,0,0,0)
And so on.
How could I accomplish this?

A very interesting topic, "quantification of randomness" in mathematics it is sometimes reffered to as "complex theory" (although it is more about pseudorandom than randomness) that is based on saying that a complicated series is more random and then there are tests for randomness in Statistics and perhaps the most intriguing test related to information theory -"entropy"(as also being of relevence to and result of second law of thermodynamics), while there are also random numbers generators (pseudorandom numbers generators) and true random numbers generators using quantum computing.
So, what I've been trying to, is making a complete list of all available algorithms or books or even random number generators that will allow me to tell me how much random a series is, allowing me to "quantify randomness".
There are 125 unique infinite series which are pseudorandom that I have discovered and generated based on a rule, now how do I test for randomness and quantify it? If the series is random or there is probably a pattern, or something that will allow me to predict the next number in the series given I don't know what the next number is.
Now, do anyone know of any github links based on any of the above? ^ (like anything related to quantifying randomness in general that you think will be helpful). A book/books on quantifying randomness will be very very helpful too. Actually anything at all...
(Also, Any coding language will do if it is able to make use of any existing algorithms for computing randomness, I have used Python for generating 125 unique infinite series which are pseudorandom-like, so is there a way already available to check how much random these series are (programmatically) or what do you suggest I should do...)
I didn't try much as of yet but what I'm planning to is first being able to plot the data (infinite sequences) get images (descriptive statistics to the rescue) to tell me if the data is first looking like random noise, although it is kind of already as from the way I computed it but essentially being able to convert one kind of data to another and see if it is behaving like noise or not.
Then there are measures such as based on compression's (something like Kolmogorov complexity) and the ways algorithms might have been used to determine how much random pi could be? I'm looking into Entropy as well, books, reading stuff and also exploring cryptographic ways but all of these are research work, am yet to arrive at developing proper and more complete ways of also being able to implement all of it programmatically and I need as many ways of being able to do it as possible.
Below is a SAS proc Mixed code generated by JMP. Both JMP and SAS give me a confidence interval for the variance components (in the table "covariance parameter estimates"). I would like the degrees of freedom in the output, or at least a formula to calculate them. Can anyone tell me where that would be?

I have a dataframe that I am currently sorting by row id 8, however I want to adjust this so it sort it by a variable that contains a random number. See code below
cosine_similarity_matrix_df.sort_values(by=['8'], ascending=False).head(11)
I want to make it so that instead of sorting the dataframe by row id 8, it sorts depending upon the random number stored in the variable called "id". I have tried to alter the code to put the variable id instead of ['8'] but this doesnt seem to work. Is there any way i can do this
Let's assume we want to generate n samples from a multinomial distribution from given probabilities p. This works well with sample or rmultinorm. The totals can then be counted with table. Now I wonder if there is a direct way (or another distribution) available to get the result of table directly without generating complete sample vectors.
Here an example:
set.seed(123)
n <- 10000 # sample size
p <- c(0.1, 0.2, 0.7) # probabilities, sum up to 1.0
## 1) approach with sample
x <- sample(1:3, size = n, prob = p, replace = TRUE)
table(x)
# x
# 1 2 3
# 945 2007 7048
## 2) approach with rmultinorm
x <- rmultinom(n, size = 1, prob = p) * 1:3
table(x[x != 0])
# 1 2 3
# 987 1967 7046
I'm writing code that randomly generates a vector of indices, fetches a random one, then uses that index to fetch another index, and so on. However, my code seems to repeat a cycle of indices. Here is my full code:
vector<uint16_t>* genBuffer() {
vector<uint16_t>* buffer = new vector<uint16_t>(256);
std::random_device rd;
std::mt19937 gen(rd());
std::uniform_int_distribution<> distr(0, 255);
for (uint16_t i = 0; i < 256; i++) {
(*buffer)[i] = distr(gen);
}
shuffle(buffer->begin(), buffer->end(), gen);
return buffer;
}
double timeAccess(vector<uint16_t>* buff, uint64_t buffSize) {
struct timespec start, stop;
random_device rd;
mt19937 gen(rd());
uniform_int_distribution<> distr(0, 255);
auto index = distr(gen);
auto nextIndex = (*buff)[index];
clock_gettime(CLOCK_MONOTONIC, &start);
for (uint64_t i = 0; i <= buffSize; i++) {
cout << nextIndex << endl;
nextIndex = (*buff)[nextIndex];
}
clock_gettime(CLOCK_MONOTONIC, &stop);
double time_taken = (stop.tv_sec - start.tv_sec) - (double)(stop.tv_nsec - start.tv_nsec);
double avgTime = time_taken/buffSize;
return avgTime;
}
int main(int argc, char* argv[]) {
if (argc != 2) {
cout << "Please enter only one numerical argument." << endl;
return -1;
}
uint64_t buffSize = atoi(argv[1]);
auto randBuff = genBuffer();
auto timeTaken = timeAccess(randBuff, buffSize);
cout << "Average time per buffer read = " << timeTaken << " ns" << endl;
return 0;
}
Here is an example run with an argument of 25:

As you can see, the pattern eventually repeats, although it shouldn't do that.
This code is part of a cache benchmark I was asked to write for class. Here is the full code for anyone willing to try:
https://github.com/aabagdi/CacheBenchmark
As well, I'm trying to time the average time per read in ns. Am I doing that correctly? Thanks!
I thought that the shuffle_string function would have generated a new seed each time gets called (so every time the cycle repeats), but something is wrong.
What could I do to circumvent this problem?
(COMPILER: g++, OS: Windows 10 x64)
Edit: Compiling with Visual Studio my code is actually running as expected.
Edit2: As suggest in the comments by @Eljay , adding 'static' before
std::random_device rd;
and before
std::mt19937_64 mt64{ rd() };
makes my program run fine even if comping with g++.
#include <iostream>
#include <random>
using std::cin; using std::cout;
void shuffle_string(std::string& s) {
auto size = s.size();
std::random_device rd;
std::mt19937_64 mt64{ rd() };
std::uniform_int_distribution<unsigned long long int> ind_range (0, size-1);
for (auto i = 0; i < size; ++i) {
std::swap(s[i], s[ind_range(mt64)]);
}
}
int main() {
while (true) {
std::string string;
cout << "Enter the string you want to randomly shuffle:\n";
std::getline(cin, string);
if (string == "exit") { return 0; }
shuffle_string(string);
cout << string << '\n';
}
}
P.S.: I know i should always prefer std::shuffle, but i'm writing this only with the aim of learn something new (and actually this problem is something new).
Thanks, good evening.
I'm trying to implement a random walk algorithm in 2D to model COVID infections at a party/festival. The main body of my code is shown below, excluding some plots and initial conditions where I define all the initial positions (using a random uniform sampling) and initial parameters. My problem is, when I run my code and plot the various populations at different steps, for whatever reason the population of moving infected people ends up looking like the green data after several steps: 
Why does this happen? Is this something to do with the random uniform sampling? Any help is appreciated.

I need to write the name of a random user on the server to a variable.
this is about how I present this code:
import discord
from discord.ext import commands
import random
@client.command()
async def hi(ctx):
user = discord.utils.get(ctx.guild.members, name = random)
await ctx.send(user + ' hi!')
I made an array list with the following names, positions, and numbers.
ArrayList<Player> playerInfo = new ArrayList<Player>();
playerInfo.add(new Player("Wilson", 'F', 14));
playerInfo.add(new Player("Johnson", 'F', 22));
playerInfo.add(new Player("Terry", 'D', 27));
playerInfo.add(new Player("Price", 'G', 34));
playerInfo.add(new Player("Stamkos", 'F', 26));
I'm looking to make something that outputs a random name, position, and number. For example having it choose Wilson, G, 26.
I have the following to make it choose a random one of each but I don't know how to stop them from from duplicating (Positions can duplicate since there's only 3 options and I'm only showing the code on how it gets the name but the exact same code is used to get the number and position).
for(Player name:playerInfo)
{
Random genSurname = new Random();
int randSurname = genSurname.nextInt(5);
System.out.println(playerInfo.get(randSurname).getSurname());
}
Any direction would be appreciated. Thanks!
I was going through a book that explained the xorshift algorithm (I know, basic stuff). Then, while searching a little bit more on the Internet, I found that all the basic examples seem to shift the bits right the same "amount" (13, 17, 5).
For instance:
struct xorshift32_state {
uint32_t a;
};
uint32_t xorshiftTransform(struct xorshift32_state *state) {
uint32_t x = state->a;
x ^= x << 13;
x ^= x >> 17;
x ^= x << 5;
return state->a = x;
}
Is there a particular reason why in all examples they use 13, 17 and 5? Yep, I found other examples too, but this one keeps repeating, and I don't know if the numbers choose is trivial or not.

I have googled and read up on random sampling from a given population , both in probability and in python , but each of the examples have data then extraction of random samples out of population data generated.
But if I don't have the population data but just the mean and std ?
For example
| Age | Size | Mean (of Salary) | Std Mean (of Salary) |
|---|---|---|---|
| 20-25 | 15000 | 5000 | 600 |
| 25-30 | 20000 | 6000 | 700 |
From the data above , how can I extract out the random sample of 200 with python ?
What I been seeing is something like "rs.append(np.random.choice(X, 5))" but I have no X , or population to choose from.
Thanks in advanced.
I have to make a "choose your own adventure" type code for one of my classes and for my idea, I decided to make the setting take place in a carnival and have the user choose a game to play. I'm currently trying to recreate the first carnival game I chose, which is balloon pop. For this, I simply have 6 ellipses representing balloons and I want the user to press "t" to throw a dart, and there would be a 50/50 chance for them to score. How I tried doing this is by setting a variable called "outcome" equal to "int(random(1, 10))" and if the generated value is between 1-5, then they pop a balloon but if it's between 6-10, then they miss. The problem is I have the random value in the setup function and it only generates a value once. I want it so that the value would generate a new number every time the user presses "t" to throw a dart, and I'm having trouble figuring out how to do that. Is there a way generate a new value each time?
Here's the balloon pop portion of my code:
let scenes = [];
let currentScene = 0;
let outcome;
let popp = 0;
function setup() {
createCanvas(windowWidth, windowHeight);
colorMode(HSB);
outcome = int(random(1, 10));

}
scenes[1] = {

}

I am trying to recreate an actual slot machine. This slot machine has 72 possibilities on each reel. I set the payout for the combinations in the slot machine. This slot machine should have a payback of 95.13% if it were perfectly random. After several million spins, my code keeps coming back with like 99%. WAAAY out of tolerance. With that many spins, it should be plus or minus .4%. I kept double checking my code over and over for the past week. I figured there had to be an error in the pay table somewhere. Finally, i decided to iterate over every possible combination. 373,248 spins later, it came back with 95.13% exactly like it should. So, the problem is not with my pay table. It is with the randomness of it
the important bit of code i am using is:
R1=random.randint(1,72)
R2=random.randint(1,72)
R3=random.randint(1,72)
I have two datasets data1 and data2 with an id column. I want to assign a random id to each id, but this random number needs to be consistent across datasets. (rand_id for id=1 must be the same in both datasets). The objective is to get:
| id | rand_id |
|---|---|
| 1 | 0.4212 |
| 2 | 0.5124 |
| 3 | 0.1231 |
| id | rand_id |
|---|---|
| 1 | 0.4212 |
| 3 | 0.1231 |
| 2 | 0.5124 |
| 4 | 0.9102 |
I thought
DATA data1;
SET data1;
CALL STREAMINIT(id);
rand_id=RAND('uniform');
RUN;
and the same for data2 would do the job, but it does not. It just takes as seed the first id and generates a sequence of random numbers. From the STREAMINIT documentation, it seems it's only called once per data setp. I'd like to be called it in every row. Is this possible?
Currently working on a card dealing project. I want a method that deals poker hands. It should randomly pick n(5) elements and return these in a collection(?). Also desired to use Random class to achieve randomness - school orders...
public ArrayList<PlayingCard> dealHand(int n){
ArrayList<PlayingCard> hand = new ArrayList<>();
Random random = new Random();
for (int i = 0; i < n; i++) {
PlayingCard card = this.deck.get(random.nextInt(this.deck.size()));
if (!hand.contains(card)){
hand.add(card);
}
}
return hand;
}
Assignment: "Create a "dealHand (int n)" method in the DeckOfCards class that randomly picks n cards from the deck and returns them in a collection. "N" is a number between 1 and 52 that is submitted as a parameter to the assign function. This feature can be used, for example, to draw n random cards from the deck. You again choose which class / interface from the Java library you use as the return type of the method."
How do I make this method fulfill the requirements mentioned earlier, using streams, filters and what not (functional programming and lambda)?
Thanks
Create program called reallyrandom.py that has a function that takes in three arguments and prints one integer.
You will print the integer that was indexed as ‘Your random value is x’ where x = the result of the indexing.
The program should not crash if the third value is larger than the first; it should not print anything to the screen.
Code
import sys
import numpy
import random
numpy.random.seed(42)
number1 = int(sys.argv[1])
number2 = int(sys.argv[2])
number3 = int(sys.argv[3])
def randomized(a, b, c):
arg1 = numpy.random.randint(0, 10, size=a)
arg2 = arg1 * b
return arg2[c]
if number3 > number1:
pass
else:
random_value = random(number1, number2, number3)
print(f"Your random value is {random_value}")
randomized(number1, number2, number3)
Test Case Examples:
python3 reallyrandom.py 1 2 9
python3 reallyrandom.py 44 3 17
python3 reallyrandom.py 77 -3 55
python3 reallyrandom.py 2 4 10
Expected Output:
Your random value is 21
Your random value is -9

I am trying to generate random shapes of equal areas. I am following another post where random shapes are created https://stackoverflow.com/a/50751932/11078529
Is it possible to put a constraint like equal surface area while generating shaped using Bezier curve.

Skip to the open_gn() one because that's where the problem is. I want to make an app that can do statistics/random related stuff and in it, I want to create an app that can generate a random number. The app generates the number but the previous value stays and interferes with the current number being generated.
