In MATLAB, can we use ga with numerical constraint ?

It might be weird question, if i cannot perform the analytic function of constraint, i have only numerical constraint, can we use ga with this numerical constraints?

thank you very much. best regard!!

If you want to put only upper and lower bounds on your parameters, you have to fill the unused arguments with ‘empty’ values using the empty matrix, [].

For instance, to only specify the upper and lower bounds:

LB = [ ... ];       % Vector Of Lower Bounds For Each Parameter
UB = [ ... ];       % Vector Of Upper Bounds For Each Parameter 
x = ga(fitnessfcn,nvars,[],[],[],[],LB,UB)

so if I have the numerical constraint such as nonlinear constraint. what can I handle with it?

[Star Strider]

I’ve rarely used nonlinear constraints, usually only linear constraints and parameter bounds. I thought you wanted to impose parameter bounds.

Writing your nonlinear constraint function depends on what you want to do. I refer you to the documentation under Input Arguments for nonlcon. See specifically Vectorized Constraints.

Of course.

Check the ga documentation:

 help ga

 doc ga

Hope this helps.

Thank you for formally accepting my answer
