CPLEX option file

GAMS
1

Dear Friends,
I want to remove any default preprocessing in CPLEX. Moreover, any cut
must be eliminated. I need just the traditional branch and bound. What
should I do in CPLEX option file?
Friendly yours,

Hossein,

In the CPLEX options file you need set:

cuts = 0 (no generate cuts)

preind = 0 (no model presolve)

preslvnd = -1 (no node presolve)

heurfreq = -1 (no node heuristic)

baritlim = 0 (no Barrier algorithm)

There are other options that could improve the processing of the model, but I think the above options is sufficient (you can view the GAMS/CPLEX manual for details). Which other options are considering?

Regards,

Fabián
