Your code is fine.... Is there something I should be looking for?

[humyunfuad]

alpop[p][i]=chrom[i]; //I donn't understand why the program creats error in debug when coming to that line

This generates the first level: alpop=new int *[job];

And this the second:

for(int lp=0;lp<pop;lp++)
alpop[lp]=new int[pop];

This alpop[p][i]=chrom[i]; uses pop as the first level and job as the second
It's the wrong oder of levels.

By the way: use [code]Your code[/code]
