CALMA: Combinatorial ALgorithms for Military Applications

CALMA is the name of a research project setting out to determine strengths and weaknesses of a range of solution approaches to combinatorial problems. The project has been financed by the Ministeries of Defence of the Netherlands, France, and the United Kingdom in the EUCLID programme RTP 6-4 as part of CEPA 6 (Artificial Intelligence). EUCLID stands for EUropean Cooperation for the Long term In Defence.

Several research groups from the three participating countries have applied their expertise in Computing Science, Mathematics of Operations Research and Local Search to the Radio Link Frequency Assignment Problem which was chosen to serve as a testbed for development and comparison of distinct optimization strategies and methods.

More detailed information of the distinct approaches can be obtained from the various participants. Coordinator of the project was ONERA/CERT in Toulouse. Test problems and reports have been distributed among participants via the CERT ftp-server, but due to safety measures this site is only accessible by personal logins. The Eindhoven ftp-site holds documents that describe the scientific results from this project, as well as several sets of test-problems.

The following groups participate in the project:


The results of the research have been discussed on a conference concluding the project. This Calma Symposium was organized by DUT and TNO and took place on November 24, 1995, in Scheveningen. For more information, click here.


The Eindhoven ftp-site holds documents written in the context of this project. Other publications are expected to appear in regular scientific papers. Here are some references to such papers that are published or have been submitted:
