The Termination Problems Data Base collects termination problems that are being used in termination competitions.
Syntax and semantics specification
- for versions from 7.* onwards (XML format): xtc.xsd, already part of the TPDB
- for versions up to 5.*: http://www.lri.fr/~marche/tpdb/format.html
see also:
- output specification for certified categories: http://cl-informatik.uibk.ac.at/software/cpf/
Data
- version 9.0 (2014), 10.3 (2015) http://cl2-informatik.uibk.ac.at/mercurial.cgi/TPDB

TPDB problems are collected from a variety of sources, by a variety of contributors. Often, the author of the problem is not the creator of the respective TPDB file. Sometimes, TPDB file structure (directory names) have been changed.
- SRS termination problems ICFP_2010 and ICFP_2010_relative were produced by participants of the ICFP 2010 programming contest, organized by Bertragm Felgenhauer and Johannes Waldmann. All of these problems are terminating by construction. See https://www.imn.htwk-leipzig.de/~waldmann/talk/10/icfp/
Tools
- converter from pre-7 (textual) format to 7.* (XML) format: http://cl-informatik.uibk.ac.at/users/thiemann/convert.jar, usage:
java -jar convert.jar someTrs.trs > someTrs.xml
- converter from 7.* (XML) format to pre-7 (textual) format: xtc2tpdb.xsl, already part of the TPDB, usage:
xsltproc xtc2tpdb.xsl someTrs.xml > someTrs.trs
- Haskell library for reading and writing TPDB (plain and XML format) [1]
