The TPTP World
The TPTP World is a well established infrastructure that supports research, development, and deployment of Automated Theorem Proving (ATP) systems. The TPTP World has some key online components, accessible through the links in the logo images below.
If you're new to all this, you might want to start at the TPTP and TSTP Quick Guide. You could also work your way through the slides of the TPTP World Tutorial. There is quite comprehensive documentation in the TPTP Problem Library's technical manual that is also relevant to other parts of the TPTP World.
The TPTP World Needs Money If your work benefits from use of the TPTP and related projects, consider making an annual cash donation to support the TPTP. A donation can be made as an unrestricted gift (tax deductible) to the University of Miami, explicitly to support the TPTP and related projects. Read about benefits and process of making a donation. A premium support contract is also available.
Problems, Solutions, & Standards
The TPTP (Thousands of Problems for Theorem Provers) problem library is a collection of test problems for Automated Theorem Proving (ATP) systems.
The TSTP (Thousands of Solutions from Theorem Provers) solution library is a collection of solutions to TPTP problems.
TPTP Language BNF
The TPTP language is one of the keys to the success of the TPTP World. It is used for writing both problems and solutions.
The SZS ontologies provide values to specify the logical status of problems and solutions, and to describe logical data.
Online Tools and Services
TPTP2T generates lists of problems and solutions from the TPTP and TSTP libraries, with required characteristics.
SystemB4TPTP provides tools online, to prepare ATP problems.
SystemOnTPTP provides recent versions of ATP systems online, to solve ATP problems.
SystemOnTSTP provides tools online, to examine ATP solutions.
Events
The TPTP Tea Party brings together developers and users of the TPTP World. This approximately annual meeting elicits feedback to ensure that the TPTP World meets the needs of users and developers.
Slides from talks about the TPTP World (and some other aspects of automated reasoning) .
The CADE ATP System Competition (CASC) is the annual evaluation of fully automatic ATP systems - the world championship for such systems.

User Documentation
A quick guide to the TPTP problem library, TSTP solution library, and the TPTP language and standards. Some easy and hard test problems for ATP systems are listed.
The TPTP language is one of the keys to the success of the TPTP World. Read lots about the language here.
Eveything you need to know about downloading and using the TPTP problem library.
TPTP Proposals
We are working on new features for the TPTP, as explained in the following proposals. Comments from potential users will be appreciated.
TPTP Software
Many people have written software for processing TPTP format data. These links point to software I know of (please send your link if you have some software to add to the list).
Geoff's Service Tools (clone --recurse-submodules to get the JJParse submodule). A bunch of tools for manipulating the TPTP, including the JJ parser for the TPTP language (named after the Spanish software developers, Justo Fernandez Reche and José Taboada Berenguer). The JJ parser will parse TPTP files and build a useful data structure, and there are lots of "useful" API functions for interrogating and manipulating the data structure. There is no documentation for any of this yet, but the sample drivers illustrate how to use the JJ parser API.
João Paulo A. Almeida's TPTP Editor as an Eclipse Plugin.
Alex Steen's Scala parser for the entire TPTP grammar.
Tobias Gleißner's ANTLR4 grammar for the SyntaxBNF-v7.0.0.
Matthias Fuchs' NPM package for the TPTP and SystemOnTPTP.
Mark Lemay's Xtext based Java parser for the TPTP grammar.
Michael Rawson's Rust parser for the TPTP's FOF and CNF grammars.
