Sources
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.
The following are references for classical problem sets that appear in TPDB.
- TRS/SK90 Joachim Steinbach, Ulrich Kühler: Check your Ordering - termination proofs and open Problems, Technical Report SR-90-25, Universität Kaiserslautern, 1990.
- TRS/D33 Nachum Dershowitz: 33 Examples of Termination, 1995 Proc. French Spring School of Theoretical Computer Science, LNCS 909, http://www.math.tau.ac.il/~nachumd/papers/printemp-print.pdf
- TRS/AG01 Thomas Arts, Jürgen Giesl: Termination of term rewriting using dependency pairs, 2000, http://dblp.uni-trier.de/rec/bibtex/journals/tcs/ArtsG00 http://verify.rwth-aachen.de/giesl/papers/ibn-97-46.ps
- SRS/Zantema 128 string rewriting termination problems collected by Hans Zantema (2004?). They include (as z027 .. z064) a set of one-rule termination problems by Alfons Geser (Habilitationsschrift, Tübingen, 2001) and possibly Winfried Kurth (Dissertation, Clausthal, 1990)
And here are some extra bits of trivia.
- SRS termination problems ICFP_2010 and ICFP_2010_relative were produced by participants of the ICFP 2010 programming contest, organized by Bertram 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
- converter from 7.* (XML) format to HTML: xtcHTML.xsl, see explanation at http://lists.lri.fr/pipermail/termtools/2018-July/001212.html
