Solver and development framework for mixed-integer linear programs

SYMPHONY is an open-source solver for mixed-integer linear programs (MILPs) written in C. It can be used in four 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. * Through a number of different modeling languages: AMPL, GMPL, GAMS, PuLP.
