This fact affects the solution time a lot, as I guess the solver tries to optimize in such a small scale the variables. any ideas?

  Hi Makedon,

  as most computer programs, we use floating point arithmetic, so an equality constraint will be satisfied up to a given tolerance. You can change the tolerance setting for your variables through IntFeasTol.
