Hi,
I have a question. How can I calculate/estimate upper bound of random number, that a random number can generate ? Thanks in advance!

I asked this question on stack overflow, but didn't get any answers, so I'm trying here.
Does anybody know whats happening here? I tested on opera, dolphin and the factory android browser. (although it seems now to be working on opera)
The div doesn't change size, but the text somehow is shrunk…

I have this code for a arraylist of entities.
All the entities use the same random and so all of them move in the same direction. How can I change it so it generates a new random number for each entity?
public void moveFemale() {
for(int i = 0; i < 1000; i++){
random = rand.nextInt(99);

I did this to test the randomness of randint:
>>> from random import randint
>>>
>>> uniques = []
>>> for i in range(4500): # You can see I optimistic.
... x = randint(500, 5000)
... if x in uniques:
... raise Exception('We duped ' + str(x) + '…

I've read about it on a message board - Random class isn't really random. It is created with predictable fashion using a mathematical formula.
Is it really true? If so, Random isn't really random??

I am trying to generate a good random seed for a psudo-random number generator. I thought I'd get the expert's opinions. let me know if this is a bad way of doing it or if there are much better ways.
#include <iostream>
#include <cstdlib>
#include <fstream>
#include <ctime>
unsigned…

Hi, I am using .NET to create an artificial life program and I am using C#'s pseudo random class defined in a Singleton. The idea is that if I use the same random number generator throughout the application, I could merely save the seed and then reload from the seed to recompute a certain interesting…

The challenge
The shortest code by character count that will generate (pseudo)random numbers using the Middle-Square Method.
The Middle-Square Method of (pseudo)random number generation was first suggested by John Von Neumann in 1946 and is defined as follows:
Rn+1 = mid((Rn)2, m)
For example:

I am looking for a random number generator that can be biased. For instance, say I want a random number between 1-5, with the probability being:
1: Comes up 20% of the time
2: Comes up 10% of the time
3: Comes up 40% of the time
4: Comes up 25% of the time
5: Comes up 5% of the time
Is there anything…

Why do i need to create an instance of Random class, if i want to create a random number between 1 and 100 ....like
Random rand = new Random();
rand.Next(1,100);
Is there any static function of Random class to do the same? like...
Random.Next(1,100);
I don't want to create an instance unnecessaril…
