NLP model takes a very long to complete RRS feed

  • Question

  • I have a NLP model that has 202 decisions (101 reals[0, Infinity], 101 integers[0, 1]), one goal and 85+ constraints. On my workstation (Xeon E5420 (2.5GHz), 3GB of ram), it takes hours to run using Microsoft.SolverFoundation.Solvers.HybridLocalSearchSolver. Do I need a third party solver to solve this problem? Or is NLP model unsolvable?

    Please advice
