Check out the new version of Artelys Knitro! A brand-new Julia interface is now available. It relies on both Knitro and MathOptInterface most recent APIs providing an efficient and flexible model definition. This Julia interface also supports the JuMP modeling language enabling optimization problem modeling in no time!
Artelys Knitro 12 also comes with clear improvements on mixed-integer models (MIP/MINLP). Several new cut families including Mixed Integer Rouding, zero-half and clique have been implemented and add up to the already existing knapsack cuts.
Those new cuts have been tested on a subset of instances derived from CMU-IBM and MINLPLib1&2 libraries. As illustrated above, both the computation time and the number of tree search nodes generated have been drastically improved when using Artelys Knitro 12!
• A new Python function, called ‘optimize’, solving all your optimization problems using Knitro in a single call fashion
• Enhancement of the presolver including multipass methods applying successive presolve operations to fully exploit your problem structure
• The Knitro-Tuner has been extended to handle mixed-integer models to automatically identify the best parameters required to solve the most complex instances!
• Support of the MPS file format (Mathematical Programming System) enabling the resolution of a wide range of linear and quadratic problems
• General performance improvement especially for large SOCP instances
— We are pleased to announce that Artelys Knitro 13.1 is now available! Check out its improvements, especially on mixed-integer nonlinear problems (MINLP).
Artelys becomes a partner of the Grand Est Region thanks to its expertise in artificial intelligence!
— Artelys has been referenced by the Grand Est Region to assess the artificial intelligence maturity of companies in the region.
— Artelys was thrilled to organize the METIS 2 Dissemination webinar on May 31. In the course of this event, we had the opportunity to present the latest developments of the EU energy system model METIS and to discuss the future of EU energy system models with representatives from TSOs and industry.
— Artelys, in cooperation with Trinomics, prepared a study evaluating flexibility options to support decarbonisation for the Energy Community.
