Option NLPHeur missing #241

Closed 4er4er4er closed 3 months ago

4er4er4er commented 3 months ago

Dan Steffy at Gurobi has reported that an option in gurobiasl is missing from gurobi using MP:

I am currently working with a Gurobi/AMPL customer. We found that setting the Gurobi parameter NLPHeur=0 is very important for the performance of this customer's model. However, it appears that this parameter is missing from the list of parameters that can be set when calling Gurobi through AMPL.

Currently the workaround is to treat NLPHeur as undocumented and to specify it using the tech:optionnative option.
