Hello, I am currently modelling my first optimisation problem using Gecode. Apparently MinimizeScript (as well as MinimizeSpace) consider all solutions, not only the one with the minimal cost() value. As far as I understood it, the constraint(Space&) method is used to add restrictions so that the next solution is better than the current. That means that the last solution must be the optimal solution. If I want to find all optimal solutions I have to change constrain form cost_value < old.cost() to something like cost_value <= old.cost(). Are these assumptions correct? Now the real question. Is it possible to configure MinimizeScript in a way that it only prints the very last (optimal) solution? Is it possible that the commandline option -solutions is used in respect to optimal solutions s.t. -solutions 0 means "print all optimal solution", -solutions 1 "print the first optimal solution" and so on.
I am sorry if the answer to my questions is obvious but I didn't manage to find it in the docs or mailing list. Thanks for making such a great piece of software and for keeping it available for everyone! br Josef _______________________________________________ Gecode users mailing list [email protected] https://www.gecode.org/mailman/listinfo/gecode-users
