SoPlex is an optimization package for solving linear programming problems
(LPs) based on an advanced implementation of the primal and dual revised
simplex algorithm. It provides special support for the exact solution of LPs
with rational input data. It can be used as a standalone solver reading MPS
or LP format files via a command line interface as well as embedded into other
programs via a C++ class library. The main features of SoPlex are:
- presolving, scaling, exploitation of sparsity, hot-starting from any regular
basis,
- column- and row-oriented form of the simplex algorithm,
- an object-oriented software design written in C++,
- a compile-time option to use 80bit extended ("quad") precision for
numerically difficult LPs,
- an LP iterative refinement procedure to compute high-precision solution, and
- routines for an exact rational LU factorization and continued fraction
approximations in order to compute exact solutions.
SoPlex has been used in numerous research and industry projects and is the
standard LP solver linked to the mixed-integer nonlinear programming and
constraint integer programming solver SCIP.
This package contains a command-line tool to access SoPlex functionality.
