Re: [abc-users] probability

NO man its not that. Its how could make my extension generate random
numbers at runtime!!
I have to make my self more clear. In my residue I AlwaysMatch shadows
within a certain probability.

public Residue optimize() {
       probGenerated=generator.nextInt(100)+1;
       if (probGenerated<=prob)
       {
           return AlwaysMatch.v();
       }
       else
           return NeverMatch.v();
   }

This give me a problem of having the same shadows every time I run my
program. I want the random shadow match generation to be at runtime.
I hope I'm more clear this time.

I know to generate random numbers. I first did that in MSX Basic when I
10 years old :-)
