It says that iterations in fmincon active-set algorithm can violate constraints, which seems to appear in the figures above, especially the last two. So I change the algorithm from active-set to interior-point and the optimized result for Case (1)-(4) under b=2,5 and 10 are the same....
I'd like to ask about the validation of optimization using globalsearch and fmincon. I'm currently using Aspen HYSYS to get the simulation data and so be trying to connect Aspen and MATLAB to find the optimal point. However, it seems MATLAB can't find the global optimal cond...
With the initial guess for x0, I can get close but it never seems to approach my curve nearly enough. How do I know if I have a good starting guess, and is fmincon even the right approach for this problem. I have multiple data sets, for different stretch ratios (lambda_1:lam...
