Unification (computer science)

In computer science, particularly in the fields of logic programming, type inference, and automated reasoning, **unification** refers to the process of making two terms identical by finding a substitution for their variables. This concept is fundamental in various areas including: 1. **Logic Programming**: In languages like Prolog, unification is the mechanism used to match predicates and rules with arguments. When a rule is applied, unification determines what variable substitutions need to be made to make the terms match.
