A satisfiability tester for non-clausal propositional calculus. (English) Zbl 0658.68107
An algorithm for satisfiability testing in propositional calculus with worst case complexity \(2^{(0.25+\epsilon)L}\) is presented, where L can be either the length of the input or the number of occurrences of literals in the expression. The algorithm proceeds by a careful choice of the “branch” variable and has the important feature that it does not need the testing expression to be in any normal form.
