I'm trying to solve a nonlinear problem with nonlinear constraints using gamultiobj but this solver doesn't support nonlinear constraints . I looking for another solver in Matlab?
thank you
There are the non-linear regression method and the artificial neural network technique.
Check the online course "Machine Learning" by Andrew Ng and the "nntool" in Matlab.
I think performing a linearization for a nonlinear variable will look for the values that fulfill the linear relation.
MATLAB's fmincon accepts non-linear constraints
https://www.mathworks.com/help/optim/ug/fmincon.html
Also, in the documentation, gamultiobj says it takes in nonlinear constraints
x = gamultiobj(fitnessfcn,nvars,A,b,Aeq,beq,lb,ub,nonlcon) finds a Pareto set subject to the constraints defined in nonlcon. The function nonlcon accepts x and returns vectors c and ceq, representing the nonlinear inequalities and equalities respectively. gamultiobj minimizes fitnessfcn such that c(x) ≤ 0 and ceq(x) = 0. (Set lb = [] and ub = [] if no bounds exist.) gamultiobjsupports nonlinear constraints only for the default PopulationType option ('doubleVector').
