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
— As part of Le Havre Seine Métropole’s energy master plan, Artelys has worked with metropolitan services to set up a web platform for monitoring territorial energy data.
— CasADi is an open-source tool for general numerical optimization with a strong focus on optimal control and its versions 3.6.2 and higher are now compatible with Artelys Knitro 13.2.
Artelys participation to studies assessing potential contribution of African H2 to EU decarbonization objectives
— As part of the Clean Hydrogen Partnership funding programme, Artelys will participate in the JUST-GREEN AFRH2ICA project along with ten other African and European partners ready to share their know-how on hydrogen economics and technologies.
Artelys demonstrated how to perform cost-benefit analysis of new transmission assets in a smart grid during a webinar hosted by the Linux Foundation Energy and the Global Power System Transformation Consortium showing the strength of the prominent open-source grid computation tool PowSyBl-Metrix.
