摘要

Suppose we are given a set Phi of m Boolean formulas with the information that e of these formulas are unconfirmed, while the actual set of unconfirmed formulas is not disclosed to us. Let us denote by Rest(Phi, e) the family of all subsets of Phi having m - e elements. We are interested in the problem whether a Boolean formula omega is a consequence of Psi for each Psi is an element of Rest(Phi, e). More generally, given for each i = 1, ..., h a set Phi(i) of m(i) Boolean formulas and an integer 0 <= e(i) < m(i), will omega be a consequence of Psi 1 Lambda...Lambda Psi (h) for every choice of Psi(i) is an element of Rest(Phi(i), e(i))? We construct a quadratic reduction of this problem to the consequence problem in infinite-valued Lukasiewicz propositional logic L-infinity. Our reduction shows the usefulness of L-infinity for the formal handling of unreliable Boolean information.
