How can I find the optimal point of two fitness functions

I have two fitness functions and I want to maximize them 1.FH=f(a,b,h,N) 2.M=f(a,b,h,N) *a,b,h are constraints, but N is f(a) I have two questions 1.In opmtimal tool, N will be optimized or just compute in equation of N before we get a 2.How can I get the optimal point of two fitness functions by GA

thanks for answer

First of all, to maximize a fitness function, minimize the negative of the function.

Secondly, are you asking about solving two independent optimization problems, or a multiobjective problem? For two independent problems, just call the solver twice, once for each objective problem. For a multiobjective problem, see Multiobjective Optimization.
