How to set node limit for SBB?

GAMS

Hi folks,

I’m using SBB to solve a convex MINLP problem. I need to set the node limit to a large number. I use the syntax
option NodLim=100000000000;
However, GAMS says it is an unknown option. Does anyone knows how this works?
Thanks in advance.

NodLim cannot be set by a global option, you need to do it through a model suffix. See https://www.gams.com/24.9/docs/UG_ModelSolve.html#UG_ModelSolve_ModelAttributes

mymodel.nodlim = 1e6;
solve mymodel min obj using MINLP;

Hope this helps,
Michael
