Cbc

The NEOS Server offers Coin Branch and Cut (Cbc) for the solution of mixed integer linear programs in AMPL format.
Cbc has it's own User's Manual.

Cbc is an open source project that was lead by John Forrest, and is current led by Ted Ralphs.


Using the NEOS Server with Cbc and AMPL

The user must submit a model in AMPL format to solve a mixed-integer linear program (MILP). Examples of models in AMPL format can be found (among other places) on the AMPL Web page

The model is specified by a model file, and optionally, a data file and a commands file. If the command file is specified it must contain the AMPL solve command. However, the command file must not contain the model or data commands. The model and data are automatically set to (standard) named files by NEOS.
