Unification

Unification is a process used in logic and computer science to determine if two expressions can be made identical by finding appropriate substitutions for their variables. For example, if one expression involves a variable "X" and another has a specific value, unification finds what "X" should be to make both expressions match. It's like solving a puzzle by replacing unknown pieces with the right ones to fit perfectly. This technique helps in automated reasoning, programming languages, and artificial intelligence, enabling systems to recognize and connect related information efficiently.
