Places OOPS , an object-oriented parallel implementation of the interior point algorithm developed by Jacek Gondzio, Andreas Grothey and Robert Sarkissian. The code can exploit special structure of the application. The interior-point approach is one of three or four approaches being used to solve complementarity problems. The Math Programming page at the University of Wisconsin-Madison. The Optimization Technology Center at Argonne and Northwestern, and the NEOS Server , which includes the linear programming code PCx among its roster of solvers.
NEOS solves the problem and returns the results.
PCx , the NEOS project's primal-dual code. Contains links to further information on primal-dual codes. Mathematical Programming Glossary maintained by Harvey Greenberg. A group of IE students at Berkeley have built a nice interactive demo of linear programming. It allows you to enter a 2D problem, solve it, and view the results graphically.
