interfaces

— Xpress-Kalis

Artelys Kalis has been associated with the algebraic modeling language FICO® Xpress Mosel to form the Xpress-Kalis constraint programming component.
FICO® Xpress Mosel facilitates the development of models thanks to its many data connectors (text files, Excel , ODBC, Oracle) as well as its integrated development environment, Xpress Workbench.
With Xpress-Kalis, you get all the power of FICO® Xpress Mosel: define your own search strategies or your specific constraints never been so simple!
