WebMultiStart gives a choice of local solver: fmincon, fminunc, lsqcurvefit, or lsqnonlin. The GlobalSearch algorithm uses fmincon. MultiStart can run in parallel, distributing start points to multiple processors for local solution. To run MultiStart in parallel, see How to Use Parallel Processing in Global Optimization Toolbox. WebThe fmincon interior-point algorithm can accept a Hessian function as an input. When you supply a Hessian, you can obtain a faster, more accurate solution to a constrained minimization problem.
