What about increasing the error? I don't really care about having the optimal
solution, I do not need such a precision.
How can I change it ? Because if I stop it before it finds the optimal
solution, than I get no results.... I whish to be able to view a solution
even if it is not the optimal one.
Does anybody knows if such an option is possible ?
