Thousands of Geometric Problems for Geometric Theorem Provers (TGTP)

Thousands of Geometric problems for geometric Theorem Provers (TGTP) is a Web-based library of problems in geometry. The principal motivation in building TGTP is to create an appropriate context for testing and evaluating geometric automated theorem proving systems (GATP). For that purpose TGTP provides a centralised common library of geometric problems with an already significant size but aiming to became large enough to ensure meaningful system evaluations and comparisons. TGTP provides also a workbench were it is possible to test any given geometric conjecture. TGTP is independent of any given GATP. For each problem the code for each GATP (whenever available) is kept in the library. A common format for geometric conjectures, extending the i2g format, is being developed. This common format, plus a list of converters, one for each GATP, will allow to test all the GATPs with all the problems in the library. TGTP is well structured, documented and with a powerful querying mechanism, allowing an easy access to the information. All information in the library, and also the supporting formats and tools are freely available. TGTP aims, in a similar spirit of TPTP and other libraries, to provide the automated reasoning in geometry community with a comprehensive and easily accessible library of GATP test problems. The development of TGTP problem library is an ongoing project.
