Release of Xpress-Kalis 2008.3

Fair Isaac and Artelys announced today the issuing of the new software release of Xpress-Kalis 2008.3 Constraint Programming Module. One can find a ready-to-use practical module based on advanced added-value constraint programming techniques, which supplies an acknowledged achievement regarding both performance and flexibility with regard to discrete combinatorial problems. Xpress-Kalis is an excellent tool on the market designed for the resolving of scheduling and resource allocation matters.

Performance Improvement Resolving of Scheduling Issues

Thanks to a performance gain concerning scheduling issues, Xpress-Kalis is now able to process questions associated to very complex combinatorial aspects. The principal technical innovations are the following:

• Possibility to choose between alternative resources,
• Pre-emptive scheduling of tasks (with the possibility to interrupt tasks),
• Possibility to use non-constant profiles of resources.

These innovations enable to obtain a substantially real representation of the true problems and significantly more accommodating modelling product.

Improvement of both Propagation and Research Algorithms

The Xpress-Kalis 2008.3 release has strongly upgraded its solver possibilities, and therefore has largely increased the software's generic performance:

• Search tree: a big improvement in the ease of use thanks to the building-up search strategies by default,
• An increased flexibility of specific strategies elaborated for advances users,
• Providing the possibility to carry-out infeasibility analysis.
