How to find out the default solvers used?
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

Dear Sara!
In GAMS IDE
Left upper corner -> "file"
inside "option"
inside "solver"
Make Your choice!
All the best! Andre

RE: How to find out the default solvers used?
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
