Prolog has many built-in features for AI programming, such as backtracking, data structures, and pattern matching.
This language is widely used for AI and has been implemented in many AI apps.
Prolog also is a free and open-source programming language that is available on many platforms.
Prolog is a logic programming language implementing backward chaining on Horn clauses.
It is somehow different from a “usual” programming language in the sense that it has no keywords (only a few pre-defined predicates) and a program consists simply of a set of clauses.
A clause may be a fact we know about the world.
Why It's Hard to Learn: Prolog's paradigm, based on logical rules and declarative programming, contrasts with the imperative style of most languages.
Mastery of Prolog requires a firm grasp of symbolic reasoning and a willingness to dive into its unique approach.
