This mechanism has been used with the\nOtter and Prover9 theorem provers, both for interactive formalizations and for\nhuman-assisted proving of open conjectures in small theories. In this work we\nexplore the use of watchlists in large theories coming from first-order\ntranslations of large ITP libraries, aiming at improving hammer-style\nautomation by smarter internal guidance of the ATP systems. In particular, we\n(i) design watchlist-based clause evaluation heuristics inside the E ATP\nsystem, and (ii) develop new proof guiding algorithms that load many previous\nproofs inside the ATP and focus the proof search using a dynamically updated\nnotion of proof matching. The methods are evaluated on a large set of problems\ncoming from the Mizar library, showing significant improvement of E's standard\nportfolio of strategies, and also of the previous best set of strategies\ninvented for Mizar by evolutionary methods.","url_abs":"http://arxiv.org/abs/1802.04007v2","url_pdf":"http://arxiv.org/pdf/1802.04007v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"proofwatch-watchlist-guidance-for-large","repo_url":"https://github.com/ai4reason/eprover-data","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
