The COIN-OR Open Solver Interface is a uniform API for interacting with callable solver libraries. It supports linear programming solvers as well as the ability to "finish off" a mixed-integer problem calling the solver library's MIP solver. . Supported solvers: * COIN-OR LP solver (OsiClp) * DyLP (OsiDylp) * the Volume Algorithm (OsiVol) . Osi is part of the larger COIN-OR initiative (Computational Infrastructure for Operations Research). . This package contains the binaries and libraries.
