We consider the problem of evaluating a boolean function P(x1,…,xn), by asking queries of the form “xi=?”, and receiving answers which may not always be truthful. Assuming that the total number of lies does not exceed E, we present an algorithm with cost O(n+sPE+tPE), where sP is the maximal size of a minterm of P(x) and tP ‘is the maximal size of a maxterm. We also prove that if P is monotone, then any algorithm for evaluating P must ask Ω(sPE+tPE) queries for some input.
