This paper describes the First-Order Form (FOF) and Clause Normal Form (CNF) parts of the TPTP problem library, and the associated infrastructure. TPTP v3.5.0 was the last release containing only FOF and CNF problems, and thus serves as the exemplar. This paper summarizes the history and development of the TPTP, describes the structure and contents of the TPTP, and gives an overview of TPTP related projects and tools.
Abstract. We introduce StarExec, a public web-based service built to facilitate the experimental evaluation of logic solvers, broadly understood as automated tools based on formal reasoning. Examples of such tools include theorem provers, SAT and SMT solvers, constraint solvers, model checkers, and software verifiers. The service, running on a compute cluster with 380 processors and 23 terabytes of disk space, is designed to provide a single piece of storage and computing infrastructure to logic solving communities and their members. It aims at reducing duplication of effort and resources as well as enabling individual researchers or groups with no access to comparable infrastructure. StarExec allows community organizers to store, manage and make available benchmark libraries; competition organizers to run logic solver competitions; and community members to do comparative evaluations of logic solvers on public or private benchmark problems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
