Sorry, you are totally on the wrong track here, please consult an example (just search the mailing list for a discussion of this).
Constraints are implemented as propagators, and propagators use views not variables. Christian From: users-boun...@gecode.org [mailto:users-boun...@gecode.org] On Behalf Of amina kemmar Sent: Saturday, August 29, 2009 12:23 PM To: us...@gecode.org Subject: [gecode-users] A constrain with 3 IntVar Hi, I am writing a new constraint "NewConstraint", which takes 3 IntVar as arguments : #include <algorithm> #include <gecode/int.hh> namespace Gecode { using namespace Int; void NewConstraint(Space& home, IntVar x0, IntVar x1, IntVar x3) { if (home.failed()) return; // Creation of an array x, which contains the 3 variables x0,x1,x2; // ..... // ViewArray<IntView> xv(home,x); // GECODE_ES_FAIL(home, NewConstraint::Diff<IntView>::post(home,xv)); } } To post the constraint i need to create a ViewArray, but i don't understand how to create an IntVarArg containing these variables ?
