This paper presents a new generic filtering algorithm that simultaneously considers n conjunctions of constraints as well as those constraints mentioning some variables Yk of the pairs X,Yk (1≤k≤n) occurring in these conjunctions. The main benefit of this new technique comes from the fact that, for adjusting the bounds of a variable X according to n conjunctions, we do not perform n sweeps in an independent way but rather synchronize them. We then specializes this technique to the non… CONTINUE READING
