MPS/LP Parameters

If you are solving an MPS/LP problem, some additional parameters are available.

You can set most Xpress Optimizer controls as parameters with names beginning XPRS_ or XSLP_. For example, XPRS_CUTSTRATEGY. Refer to the Xpress Optimizer Reference Guide for full details.

Several other parameters are specific to MPS/LP problems:
  • PROBLEM_FORMAT: This indicates the format of your optimization problem. If it is not set, it defaults to MPS - other valid values are:
    • MPS: MPS or XMPS format.
    • MPS.GZ: Compressed MPS or XMPS format.
    • LP: LP format.
    • LP.GZ: Compressed LP format.
  • OBJECTIVE_SENSE: Indicates whether the objective function should be minimized or maximized. Valid values are:
    • MINIMIZE
    • MAXIMIZE
    • DEFAULT: Takes the value as specified in the MPS or LP file. MINIMIZE if unspecified.
  • SOLUTION_FORMAT: Indicates the format in which you wish to download results:
    • SLX: SLX format.
    • SLX.GZ: Compressed SLX format.
