Description:

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)
