Postprocessing of GMPL models

Reported by: xypron Owned by: mjs

Component: Osi Base Class Version: 0.96.1

Description

GMPL can be used to define models, which can be imported via method OsiSolverInterface?->readGMPL.

GMPL can also be used to define post processing, which can be used for efficient output of the results of an optimization run.

Unfortunately method readGMPL always calls mpl_terminate(gmpl). Hence it is not possible to execute the postprocessing of the GMPL model.

I suggest to add an optional parameter to readGMPL which allows to keep the model opened and a new method to OsiSolverInterface? to execute the postprocessing phase in GLPK.

I think this would be great! I would like to be able to use cbc and/or symphony with MathProg? including the postprocessing. Therefore I second this proposal.
