The TPTP World – Infrastructure for Automated Reasoning

Abstract

Abstract. The TPTP World is a well known and established infrastructure that supports research, development, and deployment of Automated Theorem Proving (ATP) systems for classical logics. The data, standards, and services provided by the TPTP World have made it increasingly easy to build, test, and apply ATP technology. This paper reviews the core features of the TPTP World, describes key service components of the TPTP World, presents some successful applications, and gives an overview of the most recent developments.

Higher-order aspects and context in SUMO

“…These systems are all available online via the SystemOnTPTP tool [51]. Exploiting the TPTP World infrastructure [70], all experiment runs reported in Table 2 were done remotely at the University of Miami on 2.80GHz computers with 1GB memory and running the Linux operating system. The timeout in each run was set to 300 seconds.…”

The CADE-26 automated theorem proving system competition – CASC-26

“…(There are very few propositional problems in the TPTP anyway.) -Each TPTP problem has a difficulty rating [15] that is based on ATP system performance data in the Thousands of Solutions from Theorem Provers (TSTP) solution library [12]. The ratings range from 0.00 (easy) to 1.00 (unsolved).…”

Standalone Tactics Using OpenTheory

“…An impressive example of providing reasoning infrastructure over the internet is System on TPTP [15], which enables a user to remotely execute a collection of automatic theorem provers on a problem expressed in a standard format. The usual scenario is to decide the validity of first order logic formulas (TPTP format), but there is also support for higher order terms (THF format), and for returning proofs expressed in a standard language (TSTP format).…”
