lp_solve is a free software command line utility and library for solving linear programming and mixed integer programming problems. It ships with support for two file formats, MPS and lp_solve's own LP format.[1] User-defined formats are supported via its "eXternal Language Interface" (XLI)[2] lp_solve also supports translating between model formats using the -w series of command line switches[3]
lp_solve uses the simplex method for linear programs, and branch-and-bound for mixed integer programs. Multiple pivoting strategies are supported, including devex. lp_solve also features a pre-solver that can remove redundant variables and remove or tighten constraints.
The lp_solve project also features an integrated development environment called LPSolve IDE, for Microsoft Windows.
