OQNLP

OQNLP is a solver designed to find global optima of smooth constrained nonlinear programs (NLPs) and mixed integer nonlinear programs (MINLPs) developed by OptTek Systems, Inc (http://www.opttek.com/ ).  It solves the problem from multiple starting points, and keeps track of all feasible solutions found by that solver, and reports back the best of these as its final solution.  The starting points are computed by a scatter search implementation.  OQNLP can solve NLP, DNLP, RMINLP, and MINLP model types.  The solver manual is Oqnlp.pdf.
