I am trying to solve a 'Constrained Non-linear' objective function having 2 variables (Height and Thickness).
But as figure shows, function contains multiple local minima.
I have tried using all applicable solvers from MATLAB Optimization Toolbox. Also tried Hooke-Jeeves pattern search algorithm.
But calculated solution is always one of the local minima unless starting point / initial guess is given somewhere closer to the actual solution (Global Minimum).
Could you please suggest me any better solvers or optimization algorithms?
Thanks in advance. 🙂
