KNITRO for Mathematica, a new application package for large-scale
nonlinear optimization, is now available for download from the
Wolfram web store. Complete with active-set and interior-point
algorithms within a local solver, it solves general nonlinear
constrained, linear programming, quadratic programing,
unconstrained, and least squares problems, as well as systems of
nonlinear equations.

Key features include:

* Newton-based methods, including BFGS, SR1, and L-BFGS, that
rapidly converge to high-precision local solutions
* An option requiring that every iterate is feasible with respect
to inequality constraints and variable bounds
* Easy crossover from interior-point to active-set algorithms for
determining vertex solutions
* Linear algebra operations for iterative (conjugate gradient)
and direct (sparse factorization) methods
* Automatic starting-point selection

Developed and supported by Ziena Optimization, Inc., KNITRO for
Mathematica requires Mathematica 5.1 or higher for Windows,
Linux, or Sun Solaris platforms.

A 30% discount will be applied to all purchases made before June
30, 2006.
