WebFirst-order logic (FOL) is a logic that gives us the ability to quantify over objects. You will often see FOL called rst-order predicate logic or rst-order predicate calculus. These are all di erent names for the same thing. The examples in the last section can be encoded in FOL 8x(Rich(x) )9y[Owns(x;y) ^Car(y) ^Nice(y)]) and WebThe question arises as to whether there exists an algorithm for determining whether a given formula of first-order logic is satisfiable, or indeed finitely satisfiable. This question was answered negatively in 1936 by Church and Turing (for satisfiability) and in 1950 by Trakhtenbrot (for finite satisfiability).In contrast, the satisfiability ...
