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.
Artelys provides support to the French energy regulatory authority (CRE) in assessing the adequate incentive levels to foster distribution networks performance for TURPE 7
Artelys has conducted a quantitative assessment to inform target levels proposals for TURPE 7, examining past performance and the impact of integrating smart meter data (Linky) into indicators measuring the quality of energy supply.
The MARI project is growing
In recent months, several new European TSOs have successfully joined MARI, the pan-European mFRR activation platform whose market clearing engine was developed by Artelys.
