Hi Tommaso, Your brancher has a bug ;-) It claims to have a certain number of alternatives (as defined by the alternatives() member function of the brancher's choice object class) but later alternatives are tried (via the commit() function) during search which have a number larger than what alternatives() reports.
Maybe you do not properly initialize the number of alternatives in your choice class?

Hint: running the same setup without Gist results in the following error Exception: Space::commit: Attempt to commit with illegal alternative. Stopping... I therefore ask for your help :) Tommaso _______________________________________________ Gecode users mailing list users@gecode.org https://www.gecode.org/mailman/listinfo/gecode-users
