Stochplam

Stochplam is an add-on to the algebraic modelling language PLAM by Alexander Bockmayr and Peter Barth.

The modifications extend PLAM to handling stochastic programming problems. Stochplam will output either SMPS-files, or an intermediate file format readable by the open source nested Benders solver BNBS .

PLAM

Plam (ProLog And Modelling) is an open source modelling language written in prolog. Plam may be found at ftp://ftp.mpi-sb.mpg.de/pub/guide/staff/barth/plam/.

requirements

In order to run stochplam, plam is needed. See above for download details. Plam in turn requires a Prolog interpreter.
The recommended one is SWI-Prolog, an open source implementation.

usage

Stochplam may be used and modified free of charge for any purpouse. It may not be redistributed at a fee. Do note that stochplam is an addon to PLAM, and that you must adhere to the usage rules of PLAM.

A short note describes how stochplam works.

download

Stochplam may be downloaded here. It has only been tried on sun solaris and linux, but as it runs in SWI-Prolog, it should work on other systems as well.
