FortMP is a software package for solving large-scale optimization problems.
Its robustness has been explored and published in the Mathematical Programming journal.
[1] FortMP is available as a standalone executable that accepts input in MPS format and as a library with interfaces in C and Fortran.
The main algorithms implemented in FortMP are the primal and dual simplex algorithms using sparse matrices.
Mixed integer programming problems are solved using branch and bound algorithm.
