The TPTP problem library, v9.3.1 — a preservation copy

The TPTP (Thousands of Problems for Theorem Provers) is the standard library of test problems for automated theorem proving, created by Geoff Sutcliffe and Christian Suttner and maintained by Geoff Sutcliffe, with problems contributed by many authors over three decades. Its home is https://tptp.org, and that is where it should be obtained, cited and credited.

TPTP-v9.3.1.tgz is the distribution exactly as tptp.org publishes it at https://tptp.org/TPTP/Distribution/TPTP-v9.3.1.tgz, verbatim, byte for byte: problems, axioms, generators, documents and the TPTP2X utility, in their original TPTP syntax (CNF, FOF, TFF, THF). SHA256SUMS lists its checksum.

Why this copy exists

This copy is made to ensure that this knowledge will not be lost by humanity. The TPTP is a unique, decades-long record of mathematical and logical problems and of the reasoning systems built to solve them, and it is hosted in essentially one place. This mirror is a safeguard against that single point of failure; it is not a replacement for the original, and it is not an endorsement by the TPTP's authors.

Copyright — please read

The copyright of this material is restricted, and its exact scope for your use is unsure: check it before you rely on this copy. The TPTP is not under an open licence, which is why the licence of this dataset is marked other. Its own terms, in Documents/ReadMe inside the archive, are:

The TPTP is copyrighted 1993-onwards, by Geoff Sutcliffe & Christian Suttner. Verbatim redistribution of the TPTP and parts of the TPTP is permitted provided that the redistribution is clearly attributed to the TPTP. Distribution of any modified version or modified part of the TPTP requires permission.

This copy relies on that permission: it is verbatim and attributed to the TPTP. Nothing here grants you any further right. In particular:

• All rights remain with Geoff Sutcliffe & Christian Suttner and with the authors of the problems, credited in the header of each file.
• Distributing a modified version, or a modified part, requires their permission.
• Prefer the original distribution at https://tptp.org whenever it is reachable, and check the terms published there.
• Cite the TPTP as tptp.org asks — G. Sutcliffe, The TPTP Problem Library and Associated Infrastructure. From CNF to TH0, TPTP v6.4.0, Journal of Automated Reasoning 59(4), 2017 — and the references in each problem's header.
• If you are a rights holder and want this copy changed or removed, open a discussion on this dataset and it will be taken down.

sympy-extras-benchmarks reads the arithmetic (ARI) domain of this distribution. It downloads from tptp.org, and uses this copy only when tptp.org cannot be reached or when its user explicitly asks for the Hugging Face mirrors.
