in GA ... How can I define my problem constants once ? and how can I know the final values of the other variables (not the objective function)

Hello, I am using GA, with some integer variables and nonlinear constrains, I stated all the work in the same .m file (the output function, the nonlinear constrains function, and the fitness function) I found that I have to repeat the definition of my problem constants three times (one inside each function loop), which make my code so long, 1- How can I set/define my problem variables only once for all functions ? 2- After the optimization stop, can I know the values of all variables in the workspace as it the case of the usual MATLAB runs ? 3- How can I display/plot the final values of the variables which are neither the objective function nor from nvars ? thanks in advance, Mamdouh

If you use nested functions you can share the parameters among the objective, constraint, and output functions. Your main function should have exta outputs that give the values you are interested in, such as the values of all the variables in the workspace and anything else you like.
