Baron License error

Post by fahime110 »

I am a student using a valid Community Academic License. I am having an issue with the BARON solver when running a MINLP model. It says I do not have a valid license and does not run. Below is my error.

I thought my community license does have the BARON solver included. What can I do?

Please help me.
ERROR below

The error message is slightly misleading, it probably failed because the model you want to solve is too big for the community license. See ... ver_Limits for the model size limits for the community license. BARON has tighter limits than GAMS: "Antigone, Baron, and LindoGlobal require m≤300, n≤300, and nlnz≤100 with a community license."

SCIP is the only global solver that works with the GAMS community limit ( m≤5000, n≤5000).
