While implementing genetic algorithm for finding the global minimum for a variable 'y' (which depends upon both x and z), I want to optimise only x and not z. I want to input z from the main code and pass it to my fitness function. Can this be done?

Why the value of variables optimized using ga (genetic algorithm) are always different from 0 (but something like 0,00123) even if 0 would be more convenient?
