This is a direct search method that does not use numerical or analytic gradients as in fminunc (Optimization Toolbox). The algorithm is described in detail in fminsearch Algorithm. The algorithm is not guaranteed to converge to a local minimum.When I run the fminsearch for each block, the code is: [a,fval,exitflag,options] = fminsearch(fun,x0,options) The problem is that the optimization always stops prematurely. It does not respect my set maximum number of iterations, nor my set tolerance level. It always exits before, with fval >> TolFun and number of iterations << MaxFunEvals.3. You can't tell fminsearch to consider only integers. The algorithm it uses is not suitable for discrete optimization, which in general is much harder than continuous optimization. If there are only relatively few plausible values for your integer parameter (s), you could just loop over them all, but that might be too expensive.The fminsearch documentation doesn't make this clear. None of the examples in the documentation are examples of distribution fitting.

The algorithm is not guaranteed to converge to a local minimum. 1 Comment. Torsten on 28 Apr 2016. fminsearch can not handle constraints that a certain variable to be optimized is an integer. Choose a reasonable range for this parameter (say 1,2,3,4,...,100), run fmincon with this parameter set to 1,2,3,4,5... 100 (thus 100 times) and choose the case out of the 100 results where "minfn" is minimal.The fminsearch algorithm uses a special initial simplex, which is an heuristic depending on the initial guess. The strategy chosen by fminsearch corresponds to the -simplex0method flag of the neldermead component, with the "pfeffer" method. It is associated with the -simplex0deltausual = 0.05 and -simplex0deltazero = 0.0075 parameters.In this video we show 4 different ways to use/call Matlab’s ‘fminsearch’ function to perform unconstrained optimization.Topics and timestamps:0:00 – Introduc... The fminsearch function is similar to fminbnd except that it handles functions of many variables.
