Release of Xpress-Kalis 2008.3
Artelys and Dash Optimization (member of the Fair Isaac Corporation)
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.
