Visualizing Automated Theorem Proving: An Educational Web-Based Tool for Propositional Logic

Resolution is a fundamental technique in logic and plays a crucial role in automated reasoning and artificial intelligence. It serves as the foundation for many theorem-proving techniques and inference mechanisms. That is why we developed an educational tool that visually demonstrates resolution in propositional logic, helping students understand and engage with these fundamental concepts interactively. In this paper, we present the design and development of a web application for the automated proving of propositional formulæ. The application visualizes the proof process using both tree and table notations. The tool has been developed with the needs of computer science students in mind and has been tested and evaluated based on their feedback.
