Webunderlie approximate reasoning. We have calculated the fuzzy truth values and compare the results of di erent operations (conjunction, disjunction etc) with the approach to Baldwin’s (1979) and with the help of modus ponens law (If p !q and p0then q0.). There are many chemical reactions that are very sensitive and a little change WebMany AI problems, when formalized, reduce to evaluating the probability that a propositional expression is true. In this paper we show that this problem is computationally intractable even in surprisingly restricted cases and even if we settle for an approximation to this probability.We consider various methods used in approximate reasoning such as …
