Does the initial population matrix have to satisfy constraints genetic algorithm matlab

3 views (last 30 days)
Is it possible to give MATLAB an initial population matrix which does not satisfy the constraints?
Will MATLAB be able to automatically weed out the childs which do not satisfy the constraints?
Thanks

The initial population matrix does not have to satisfy the constraints.
Subsequent generations will, at least in my experience.

My pleasure!
I am not certain that it checks initially, however in my experience, the entire matrix conforms to the constraints after the first iteration. I have not examined the code (assuming that is even possible) to determine if it checks before the first iteration.

GA satisfies inequality and nonlinear constraints asymptotically. GA makes neither assumptions nor guarantees that the population members at any one generation will satisfy them.
Pure bounds are different. I believe ga will weed-out initial population members outside the bounds and produce children that satisfy them.
You can check all these things yourself by using a custom Output Function to retrieve the population matrix at the successive generations.
