COIN-OR solver for mixed-integer linear programs (shared libraries)
SYMPHONY is an open-source generic mixed-integer linear programs (MILP) solver, callable library, and extensible framework for implementing customized solvers SYMPHONY has a number of advanced capabilities, including the ability to solve multi-objective MILPs, the ability to warm start its solution procedure, and the ability to perform basic sensitivity analyses. . SYMPHONY is part of the larger COIN-OR initiative (Computational Infrastructure for Operations Research). . This package contains the shared libraries.
