Webcate,” or “first-order,” logic. Predicates are functions of zero or more variables that return Boolean values. Thus predicates can be true sometimes and false sometimes, depending on the values of their arguments. For example, we shall find in predicate logic atomic operands such as csg(C,S,G). Here, csg is the predicate name, and Web7.2. The Universal Quantifier¶. What makes first-order logic powerful is that it allows us to make general assertions using quantifiers.The universal quantifier \(\forall\) followed by a variable \(x\) is meant to represent the phrase “for every \(x\).”In other words, it asserts that every value of \(x\) has the property that follows it. Using the universal quantifier, the … WebNov 25, 2024 · Predicates in Computer Science. 1. Introduction. A predicate asks a question where the answer is true or false or, said another way, yes or no.
