OptQuest is a simulation optimization engine, built on a truly unique set of powerful algorithms and sophisticated analysis techniques including metaheuristics optimization, evolutionary algorithms, tabu search and scatter search, to name a few. The OptQuest WebAPI provides access to the OptQuest engine via a web server hosted on AWS. The available endpoints make it possible to explore problem search spaces for any (simulation) optimization without a custom wrapper to serve as the interface between your simulation and the OptQuest Engine.
