AI Planning & Logic: Algorithms and Search Techniques

Backward Chaining Algorithm Explained

Backward chaining is a reasoning technique used in Artificial Intelligence (AI) and expert systems. It starts from the goal (what we want to prove) and works backward to find facts or rules that support it. It is commonly used in logic programming, rule-based systems, and Prolog.

Legal Systems and Accounting Standards

Code Law vs. Common Law Systems
