The Incredible Proof Machine: A Visual Tool for Logic Proofs Released

Visual Proof Construction

The Incredible Proof Machine is a new tool designed for visually constructing proofs in different logical systems, including propositional and predicate logic. Users interact with the system by adding and connecting blocks that represent individual proof steps. A proof is considered complete when the conclusion block turns green, indicating a valid logical derivation.

Simplified Theorem Proving

The primary goal of The Incredible Proof Machine is to make the process of creating proofs more engaging and accessible, particularly for those new to computer-aided theorem proving. It bypasses the need to learn the specific syntax of established theorem provers like Isabelle, allowing users to focus on the logical structure of the proof itself. The interface supports drag-and-drop functionality for connecting proof elements.

Current Limitations and Future Plans

Currently, proofs created within The Incredible Proof Machine are saved only in the user's browser. This means that proofs will be lost if browser local storage is cleared or if a private browsing session is used. The developers have indicated plans to implement server-side saving of user progress in a future version of the tool.

Open-Source Development

The Incredible Proof Machine is released as Free Software, encouraging community contributions. The project was primarily developed by Joachim Breitner, with assistance from colleagues and friends. Academic information and further details are available through associated publications.
