Many thanks to Andrew for this point.

It works really!

I split a SUMPRODUCT of two large matrix into the SUM of the results of several smaller SUMPRODUCT of the colums of the matrix.

It works well.

I suppose that he is sending a AMPL program. Is it possible to get this AMPL code? Do you have any suggestion about converting spreadsheet models in AMPL?

Thank you ]]>

just wanted to let you know that the current download link on your home page (“The latest stable version, OpenSolver 2.8.6 (6 Mar 2017)”) actually initiates the download of version 2.8.5. (Of course, Version 2.8.6 is directly available at sourceforge.net)

Regards,

Michael

I would like to know that what is the maximum variables and constraints that Opensolver
