Gurobi options in GAMS

Answered

I've recently moved to Gurobi and we use GAMS.

Have been struggling to implement Gurobi options, is there a way to use Gurobi options directly? With a file or something like that.

For instance, I want to use the following options and have not found a GAMS correspondence:

Scaleflag;

MIPFocus;

Thank you in advance,

You can create a solver options file that contains the Gurobi-specific parameters you want to use. For example:
```
Model mymodel / all /;

$onecho > gurobi.opt
mipfocus 1
scaleflag 2
$offecho
mymodel.optfile = 1;

option Solver=gurobi;
solve mymodel using mip minimizing z;
```
