KNITROKNITROLinear and quadratic programming, unconstrained and constrained nonlinear optimization, least squares, nonlinear systems of equations
KNITRO is a software package for finding local solutions of continuous, smooth optimization problems, with or without constraints. For convex problems a globally optimal solution is obtained.
KNITRO has been designed for solving large-scale problems with thousands of constraints and variables. It offers both iterative and direct solution of linear systems, an option to enforce feasibility during the optimization process and multiple derivative approximation options.
The prefered interface is via the AMPL modeling language. KNITRO can also be used as a callable library from a C/C++ or Fortran program and is designed to be easily embedded in such programs. The callable library interface requires the user to specify routines for evaluating functions, and also perhaps, gradients and Hessians in C, C++ or Fortran.
KNITRO offers many types of licenses including both academic and value added reseller licenses as well as standard commercial licenses. KNITRO also offers a free student/evaluation edition. To try out KNITRO click here.
