Hi Denys, I think the problem is that the Matrix constructor copies the IntArgs array, so that when you modify MC you aren't changing C itself. (Whether it ought to do this or not is another question.) One solution is to instead write:
IntArgs C(4*4, 7, 1, 3, 4, 8, 2, 5, 1, 4, 3, 7, 2, 3, 1, 6, 8); linear(*this, C, X, IRT_EQ, N); Cheers, Chris _______________________________________________ Gecode users mailing list [email protected] https://www.gecode.org/mailman/listinfo/gecode-users
