....but some coefficients of the left hand side are different from 0 and 1. The second description consists of seven extended clauses, that is inequalities of the form L 1 Delta Delta Delta Lm k, which express that at least k out of m literals L 1 ; Lm have to be true [Hoo92] In [Bar93a, Bar93b] a constraint solver for 0 1 constraints is presented that computes for a given linear 0 1 inequality an equivalent set of prime extended clauses. Given a set of prime extended clauses (S) for a 0 1 set S, testing solvability and entailment becomes very easy. The set (S) however, may be ....
