Hi Sara
- You can see in the GAMSIDE what the available solvers are: File – Options – Solver. Those with a dot are available (those with – not). You can set the default solver for a specific problem (e.g. NLP) by clicking on the dot in the line with your solver of preference. I suppose GAMS just takes the first solver in the line.
- You can run gamsinst.exe (even if GAMS is already installed) from your GAMS directory and it will show the solvers it chooses as default.
- If you don’t explicitly choose one either in the GAMSIDE or using gamsinst.exe, and you want to solve your model with a non-default solver you can use an option in your model file specifying the solver. (e.g. Option nlp = PATHNLP;)
Hope this helps
Cheers

Subject: How to find out the default solvers used?
Hi,
i'm solving two models, one MIP and another that is an NLP.
how can i find out what are the default solvers that are used by GAMS to solve the models?
Thanks,
Sara
