Artelys Knitro is a commercial software package for solving large scale nonlinear mathematical optimization problems. KNITRO – (the original solver name) short for "Nonlinear Interior point Trust Region Optimization" (the "K" is silent) – was co-created by Richard Waltz, Jorge Nocedal, Todd Plantenga and Richard Byrd. It was first introduced in 2001, as a derivative of academic research at Northwestern University (through Ziena Optimization LLC), and has since been continually improved by developers at Artelys.

| - Artelys Knitro is a commercial software package for solving large scale nonlinear mathematical optimization problems. KNITRO – (the original solver name) short for "Nonlinear Interior point Trust Region Optimization" (the "K" is silent) – was co-created by Richard Waltz, Jorge Nocedal, Todd Plantenga and Richard Byrd. It was first introduced in 2001, as a derivative of academic research at Northwestern University (through Ziena Optimization LLC), and has since been continually improved by developers at Artelys. Optimization problems must be presented to Knitro in mathematical form, and should provide a way of computing function derivatives using sparse matrices (Knitro can compute derivatives approximation but in most cases providing the exact derivatives is beneficial). An often easier approach is to develop the optimization problem in an algebraic modeling language. The modeling environment computes function derivatives, and Knitro is called as a "solver" from within the environment. (en)
- Artelys Knitro est un solveur d'optimisation commercial spécialisé dans la résolution de problèmes d'optimisation non linéaire. KNITRO – (nom initial) pour "Nonlinear Interior point Trust Region Optimization" (le "K" est silencieux) – a été co-fondé par Richard Waltz, Jorge Nocedal, Todd Plantenga et Richard Byrd. La première version sortie en 2001 est née des travaux de recherche menés au sein de l'université de Northwestern (par le biais de Ziena Optimization LLC) et est désormais développé par Artelys. Les problèmes d'optimisation doivent être passés au solveur sous leur forme mathématique et il est préférable de lui fournir un moyen de calculer les dérivées sous forme de matrice creuse. Knitro peut approximer les dérivées du problème mais les performances sont généralement accrues lorsque les dérivées exactes sont fournies. Il est également possible d'utiliser un langage de modélisation qui calculera automatiquement les dérivées et appellera Knitro depuis l’environnement de modélisation. (fr)
