Dear Subscribers, I try to model an algebraic problem. In fact, I try to determine the existence of Latin Squares with certain properties. Hence, my model contains a Matrix of IntVar:
Matrix<IntVarArray> mat(l, n, n); The constraint I want to post is that for all i,j in Q: (i*j) * (j*i) == i or rather mat(mat(i,j),mat(j,i)) == i I tried two different approaches, but gecode's library doesn't support the following: // this doesn't work post(home, mat(mat(i,j),mat(j,i)) == i); // this neither element(home, mat, mat(i,j), mat(j,i), i); How do I model the constraint correctly? Best, Christian _______________________________________________ Gecode users mailing list us...@gecode.org https://www.gecode.org/mailman/listinfo/gecode-users
