XpressMP

The NEOS Server offers XPRESS-MP, from Dash Associates, for the solution of linear programming problems that can be modeled in AMPL format.


Using the NEOS Server for XPRESS

The user must submit a model in AMPL format to solve a nonlinearly constrained optimization problem. Examples of models in AMPL format can be found in the AMPL library .

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. The commands file can contain any AMPL command. Printing directed to standard out is returned to the user with the output.
