The following simplex-based solvers allow some or all of the variables to be constrained to attain integer values all allow input inįramework for Constraint Integer Programming, links to CPLEX, SOPLEX, or CLP as LP solver (C)Ĭ source, various binaries, and interfacesī&C, using CPLEX, GLPK, or SOPLEX AMPL interface The description of the most widely used LP input formatĪ utility to convert this LP format to (and from) MPS Windows/Unix executablesĪ utility (extracted from lp_solve) to convert the simple LP format to (and from) MPSĪ general branch&cut library with mixed integer capability (C++) Some are listed here: plamĪ free MILP modeling environment using lp_solve as MILP solver and SWI-Prolog Several tools are necessary to deal with such problems. The LP-problem is often very high-dimensional. The general nonlinear problem (dense, sparse, nonsmooth, SIP) Semidefinite and second-order cone programming The LP-problem, also mixed integer and stochastic
