Artelys Knitro 12.3 solves nonlinear models with millions of constraints!
The latest release of Artelys Knitro provides performance improvements on all types of optimization models (from linear and quadratic to general nonlinear models) allowing our customers to solve even larger problems with millions of constraints.
These problems are notably observed in several fields such as portfolio optimization in finance, trajectory optimization for robots or autonomous vehicles, economics or optimal power flow in energy.
This enhancement derives from two major developments:
An average performance improvement of 20% for large scale nonlinear models while using the default Interior/Direct algorithm. This improvement builds on the updates provided with Artelys Knitro 12.2 which refined internal linear systems for large scale models. These features have further been enhanced in this release, with a focus on numerical stability. An average memory saving of 40% on all types of convex models when using the Interior/Direct algorithm.
Additional features of Artelys Knitro 12.3:
Updated R, Java and C# interfaces. High speedups can be expected on all models with linear and quadratic structures as they are now processed through a dedicated API. New C and Python single call functions to solve LP, QP and QCQP problems similar to functions already available for our Matlab users. Memory savings up to 50% when using the least squares interface. New diving heuristics to complement the feasibility pump heuristic for Mixed Integer Nonlinear Problems (MINLP). General improvement on nonlinear models when using the BFGS Hessian approximation.
Join us at the METIS 3 Dissemination event organized by Artelys!
— Artelys is thrilled to invite you to the METIS 3 Dissemination Event taking place on 17 April. During this online event, we will present the latest results of the METIS project and discuss the benefits of using advanced multi-energy modelling solutions such as METIS for energy and climate policymaking.
Artelys Knitro 14: new release of our nonlinear optimization solver
— We are pleased to announce that Artelys Knitro 14.0 is now available! This new version enables compagnies to solve complex non-linear optimization problems with unprecedented efficency and precision.
Artelys to participate in the demonstration of digital twins for optimal grid and market actions in Europe
— Artelys is involved in the three-year Horizon Europe project TwinEU, which aims to create a digital twin of the entire European electricity grid with a unique consortium bringing together grid and market operators, research entities and technology providers.
New method for energy mix pathway optimization problems
— Planning for the energy transition requires the ability to optimize energy system development pathways, considering complex interactions and constraints, particularly concerning interactions between sectors and vectors. In this context, Artelys has developed a new method for solving these large-scale mathematical problems.
