Random Integers, No Repeats

[dlidstrom]

I think the family of linear congruential generators (LCG) can be used to generate a sequence of numbers (they're not very random though). For example, this will generate the numbers between 0-15 in a pseude random order, twice (C#):

Code:


void Main()
{
    byte x = 15;
    byte a = 13;
    byte b = 5;
    for (int i = 0; i < 32; i++)
    {
        x = (byte)((x * a + b) & 0xF);
    }
}
