CPLEX

This is standard.

This is actually what is implemented in standard software like Gorobi or Cplex.

So the first versions of the models that we have tested, we use these standard solvers like Gorobi or Cplex.

But now we are trying to go beyond that because it's even these softwares are for the type of problem that we are solving are sometimes not enough.

So we use techniques called decomposition method.
