On Oct 14, there will be a presentation about Grooml, the simple mathematical modelling language for the Java virtual machine, at INFORMS 2008, Washington, DC (see

The release 0.2 of Combean has been published on Sourceforge. The major changes are:

- Integration with Groovy
- Grooml (Groovy mathematical modelling language)
- Redesign of the interfaces for LP-modelling
- Improved documentation and test coverage

The major enhancement by the release is Grooml, an interpreter for a simple algebraic modelling language for LP- and MIP-models. The Grooml-models can be solved with all solvers that are supported by Combean (GLPK, Clp, Cbc, ...). ... read more

A new release is planned for autumn this year which will bring the following main features:
- Integration with Groovy
- A simple modelling language 'Grooml' which is based on Groovy and which allows for the modelling of LPs and IPs in a straight-forward language, directly integrated into Groovy using the builder mechanism of Groovy.

Release 0.1 of Combean is available. Combean is a Java framework for combinatorial structures like graphs or linear programs and optimization algorithms working with these structures.

Combean is in pre-alpha state. The code has been tested with a quite comprehensive automatic test suite and is supposed to run rather stable. The API may still be subject to heavy refactoring and major planned features (especially graph theoretic algorithms) are still missing. However, the part of the software that deals with modelling of linear programs is already quite mature and you may consider using it already in the early stage of the Combean project.
