GNU Prolog

GNU Prolog is a programming environment that allows developers to write and run programs using a language called Prolog, which is especially good at solving logical and symbolic problems. Unlike typical programming languages, Prolog focuses on defining rules and relationships, letting the computer infer solutions automatically. GNU Prolog is open-source, meaning it's free to use and modify, and it includes features like a built-in compiler and constraint logic programming, making it useful for complex problem-solving tasks such as scheduling, planning, and artificial intelligence applications.
