Welcome to our new clients // 20 Dec 2014
You have to tackle a problem involving millions of variables, trillions of solutions? You look for the best solution to this puzzle in reasonable running times, the solution which maximizes your revenues, which minimizes your resources, or both? LocalSolver, our mathematical optimization solver, can help you. LocalSolver is based on a unique, revolutionary hybrid technology, which allows to provide high-quality solutions in short running times to your hardest and largest optimization problems.
Several companies, software vendors, research centers or universities have adopted LocalSolver to solve their most challenging optimization problems. Below are listed the last organizations that joined the LocalSolver community. Why not you? For more stories, please have a look to our Clients web page.
