SATViz: A Tool for Real-Time Visualization of SAT Clause Proofs

Researchers have introduced SATViz, a tool designed to visualize Boolean satisfiability (SAT) instances through graph-based layouts. The tool leverages the variable interaction graph and a force-directed layout algorithm to display the community structure of CNF formulas, which has been linked to instance hardness and clause quality heuristics. SATViz enables real-time animation of clause proofs, highlighting variables within a moving window of recently learned clauses. It can also generate new layouts with adjusted edge weights as needed. The paper describes the structure, feature set, and presents example visualizations created with SATViz. This tool is relevant for researchers in artificial intelligence and computer science, offering insights into SAT instance complexity and proof dynamics. The work was submitted to arXiv and is categorized under Computer Science > Artificial Intelligence.
