From a numerical perspective, large speedups are to be seen on some classes of ill-conditioned models. This is due to new preconditioning techniques applied to the subproblems solved by conjugate gradient method in the Knitro interior-point/barrier algorithms. Furthermore, Artelys Knitro 10.3 offers several improvements to the internal linear algebra and linear solvers used internally for better robustness and efficiency.
• Significant improvements in large-scale least-squares models, solving the instances 10 times faster!
• Improvements in the “feasibility restoration phase” used when Knitro is struggling to get feasible allowing faster detection of infeasible models.
• Overall efficiency and robustness improvements on general nonlinear models as well as significant improvements in efficiency on models with integer variables.
— A new version of Artelys Kalis is available! It comes with important improvements on allocation and scheduling problems!
— Knitro is now available for embedded systems running on ARM architectures and opens up to an even wider field of applications!
— In the context of the MOVE R&D project, Artelys releases a dataset to simulate and analyze the Northeastern American power system, ready to be used within Artelys Crystal Super Grid.
