SOLVER- programming or not?
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 Henrique |

Hi Henrique;
I found these two articles at Microsoft but did not find an imediate answer. You will probably have to do multiple solver routines via VBA but you might check out the articles deeper than I did. Thanks, Greg http://office.microsoft.com/en- us/assistance/HA011245961033.aspx http://office.microsoft.com/en-us/results.aspx? Query=solver&Scope=HP,HA,RC,FX,XT&Origin=EC0102724 91033&App =O10 -----Original Message----- Hi all.

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 - Jorma "Henrique Campos" wrote in message ... Hi all.
