Constraint programming solver for large combinatorial problems
An interactive and user-friendly hybrid MIP/CP framework for large combinatorial problems.
Artelys Kalis is an innovative constraints programming component able to solve quickly and efficiently a wide range of combinatorial problems such as scheduling, timetabling, resource allocation, equipment or network configuration, etc.
Artelys Kalis is also available in FICO™ Xpress Optimization (Xpress-Kalis).
Furthermore, if you are an academic at a degree-awarding institution, you can join our Academic Partnership to receive a special discounted package. This package includes:
• Ten fixed annual PC licenses. Each license includes the latest version of Artelys Kalis (C++ callable library), exhaustive documentation, and ready-to-use tutorial examples.
• Rights to print or copy all documentation for teaching and research purposes.
Please contact us for more information.
Key benefits & features
• Limitless linear and non-linear modeling
• Rich semantics
• Flexible modeling
• Extreme performance with highly combinatorial and constrained problems
• More problems taken into consideration
• Includes a comprehensive library of constraints and search heuristics.
• Provides specialized modeling objects, constraints and search heuristics for scheduling and resource allocation problems.
• Includes User-defined constraints, search heuristics and callbacks.
• Automatic generation of LP or MIP relaxations for faster optimization runs.
• New! Multi-threaded optimization for multi-core architectures.
• Defines a certain number of global relations (“global constraints”) over finite domain variables, including 'all-different', 'element', 'cycle', 'occurrence' (cardinality), 'equivalence' and 'implication'.
• Solves arithmetic constraints over floating point variables.
• Flexible definition of enumeration strategies: the user may choose among different branching schemes (determining the shape of the search tree), and define combinations of the built-in variable and value selection strategies with the user’s own heuristics.
• Defines high-level modeling objects to represent tasks and resources.
• Provides a fully extensible architecture to let users define their own search heuristics and constraints, even within the Xpress-Mosel language (see Xpress-Kalis).
