What Is SoPlex?

SoPlex is a Linear Programming (LP) solver based on the revised simplex algorithm. It features preprocessing techniques, exploits sparsity, and offers primal and dual solving routines. It can be used both as a standalone solver reading MPS or LP format files and embedded into other programs via a C++ class library.

SoPlex has been implemented as a part of Roland Wunderling's Ph.D. thesis Paralleler und Objektorientierter Simplex-Algorithmus (in German).
