The default algorithm that CPLEX uses for such a problem is the Barrier method. I would like to set the algorithm to be Primal Simplex. Is this possible in OPL Script? And if so, what is the command to do so?

Hi

have you tried

execute

{

cplex.lpmethod=1;

}

in the .mod

?

Yes, that works. Thank you so much! Is this information somewhere in the documentation? I sifted through a lot of the IBM OPL/OPL Script documentation and couldn't find this method.

Hi

CPLEX > Parameters of CPLEX > List of CPLEX parameters

You will see

algorithm for continuous problems

and then
