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
|
|
* routines for an exact rational LU factorization and continued fraction
|
|
approximations in order to compute exact solutions.
