What Is SoPlex?

SoPlex is an implementation of the revised simplex algorithm. It features primal and dual solving routines for linear programs and is implemented as a C++ class library that can be used with other programs. An example program to solve standalone linear programs given in MPS or LP-Format files is also included.

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