I am using genetic algorithm toolbox of matlab. My problem is mixed integer linear programming with 346 variable and 336 constrain my result vary in each run from 2.5 to 4.5.I applied constrain on the solution given by ga but constrained are not satisfied. i tried to vary generation, population size, cross over fraction and elite count but result keep on varying and constrained are not satisfying. What should i do. Any help will be appreciated. Thank you in advance.
