Artelys Knitro 12.4 further improves the interface versatility
This release does not only come with performance improvements, in particular for general nonlinear problems, but also with improvements of the interface:
- Improvement on NLP:
- New dynamic scaling of the limited-memory Quasi-Newton BFGS, more robust and efficient for all algorithms. This leads to an average performance improvement of 20% on general nonlinear instances when using this Hessian approximation.
- New Knitro API functions:
- Allow deleting or changing linear or constant structures of a problem and then re-solving.
- Allow to retrieve information about the feasibility of the variables and constraints after both the presolve and solving process, giving a detailed analysis of the complex infeasibilities in nonlinear problems.
- Allow users to provide their own customized linear algebra solver, which is useful when the problem has a very specific structure and can be solved with highly specialized routines. This feature was recently applied with success to an industrial problem and enabled a 2x overall speedup.
In addition, Artelys Knitro 12.4 brings:
- Improvement on MINLP:
- Improved heuristics strategies
- Early integer-feasible solution found on 15% more instances
- Newly supported platforms:
- Support for the new Apple M1 chip
Artelys Knitro 16.0: Model Nonlinear Problems Natively, Solve Them Concurrently
Artelys is pleased to announce the release of Knitro 16.0, a major version introducing two flagship features — a native Nonlinear Modeler and a Concurrent Solver — alongside significant performance and robustness improvements for nonlinear, mixed-integer and linear optimization problems.
