Predicates are functions that take one or more arguments and return a truth value, typically true or false, based on the properties or relationships of those arguments. They form the backbone of first-order logic (FOL) by allowing for the expression of statements about objects in a domain. In higher-order logic (HOL), predicates become even more powerful as they can take other predicates as their arguments, enabling more complex expressions and reasoning.
congrats on reading the definition of Predicates. now let's actually learn it.
