coin-or-SYMPHONY

SYMPHONY is an open-source solver for mixed-integer linear programs (MILPs) written in C. It can be used in three different main modes: * As a callable library through either the native C interface or through the Osi. * As an interactive solver using a command-line interface. * As a framework to build customized solvers for specific problem classes. SYMPHONY can be executed in either parallel (distributed or shared memory) or sequential modes and has a number of advanced features that make it unique, including the ability to * solve biobjective MILPs, * warm start the solution procedure, and * perform basic sensitivity analyses. SYMPHONY links to a number of other COIN projects for additional functionality, including: * Clp (the default solver for LP relaxations) * Osi (an interface to alternative solvers for solving LP relaxations) * Cgl (for cut generation) * CoinUtils (for reading in MPS files and various utilities)
