Hi, Somnath,

you're interested in multiobjective optimization, and GALib wasn't  
designed to do this kind of optimization. Despite this, you may still  
do multiobjective optimization by aggregating the objective functions  
in one weighted objective function. You may also give some effort and  
derive your own multiobjective GA reusing some of the GALib classes.

Good luck
