Hi, I tried to use the Nelder-mead solver for a customized optimization. I found with some initial inputs, the solver provided by accord.net can not converged. Actually the solver stops immediately after the 2nd iteration. However, if I feed the same initial input to the Nelder-mead solver provided by Microsoft Solver Foundation 3.1, the optimization can be carried on and get converged without any problem. Does anyone know how to enable the Nelder-mead solver in accord.net work in this case?
