Nonlinear constraints Multi objective genetic algorithm

Hi,

       I have been trying to apply non linear constraints in Multiobjective Genetic Algorithm(MOGA) but it looks like we can apply only linear constraints to them, is there any particular reason why non linear constraints cannot be applied??

I have been looking for such a tool as well, using the Multi-objective Genetic Algorithm with non-linear constraints, but so far have had no luck. Any feedback helps guys!

If you use fgoalattain then you can use all constraint types. The goal attainment formulation is a way to perform multi-objective optimization.

Good Luck

Sarah

This limitation on gamultiobj is documented in the function reference page. I cannot comment on why this limitation exists, sorry, I just do not know.
