Check out Direct Optimizer - a nonlinear optimization Add-In
for Excel. As an example of its performance, I solved
the famous Extended Rosenbrock test function (the "banana
valley" function) for 100000 variables in less than 20 hours
using a 266 MHz Pentium II PC with it.

You can download Direct Optimizer for free from http://www.directoptimizer.com

Hi all.
I need to create a model with Solver tool but as it allows
only 200 variable cells, do I have to program the solution
or is there any other way to do it? If not, is there
another similar software to Excel/Solver to do it with the
same easyness?
thanx
