I have been looking for quite a while for an algorithm for the GRG2 method either in a .net assembly or an algorithm i could program myself but I cant find a decent representation of the algorithm to work with.

Does anyone here have any resources they would be willing to share?

Thanks.

Sorry to answer the question I put a bounty on, but try the free Microsoft Solver Foundation. Microsoft Excel's Solver uses the GRG2 algorithm by default, and with MSF you have a .NET API for it. Note that it is not dependent on Excel in any way though.

Wow. I will check this out tonight, but if it works I owe you big time. –  John S Jul 6 '12 at 19:39
    
I am not totally sure it is using GRG2 but whatever it does it seems to work just as well. I got some help on using it at StackOverflow here. –  Craig W Jul 6 '12 at 22:56
    
Any chance you could check into this ASAP so I can get my bounty back if it is a viable solution? ;-) –  Craig W Jul 10 '12 at 16:52

The following article mentions OpenMI and GRG2 method:
