What is Dynamic Epistemic Logic (DEL)? It is a framework within logical theory that combines epistemic logic, which deals with knowledge and beliefs, with dynamic logic, which focuses on the effects of actions on knowledge. DEL explores how knowledge and beliefs change following certain actions or events, particularly in the context of artificial intelligence.

Keep reading this article, written by the AI experts at All About AI, to learn more about dynamic epistemic logic and its use in AI.

Examples of Dynamic Epistemic Logic
