*Termination and Complexity Competition 2022* http://www.termination-portal.org/wiki/Termination_Competition_2022 *Call for Participation* Since the beginning of the millennium, many research groups developed tools for fully automated termination and complexity analysis. After a tool demonstration at the 2003 Termination Workshop in Valencia, the community decided to start an annual termination competition to spur the development of tools and termination techniques. The termination and complexity competition focuses on automated termination and complexity analysis for all kinds of programming paradigms, including categories for term rewriting, imperative programming, logic programming, and functional programming. In all categories, we also welcome the participation of tools providing certifiable proofs. The goal of the termination and complexity competition is to demonstrate the power of the leading tools in each of these areas. The competition will be affiliated with IJCAR 2022 ( https://easychair.org/smart-program/FLoC2022/IJCAR-index.html) and it will be part of the Olympic Games at the Federated Logic Conference (FLoC 2022) ( https://www.floc2022.org/floc-olympic-games). It will be run on the StarExec platform (http://www.starexec.org/). The final run and a presentation of the final results will be live at FLoC. All (co-)authors of tools or benchmarks are invited (but not required) to give a 5-20min presentation of their contributions at the Workshop of Termination (WST 2022, https://sws.cs.ru.nl/WST2022) on August 12, 2022. We ask for a title and abstract by June 18, and anyone who sends this in may additionally submit a 1-2 page paper to be included in the WST proceedings (but this is not mandatory). Please use the following URL for your WST submission: https://easychair.org/conferences/?conf=wst22 We strongly encourage all developers of termination and complexity analysis tools to participate in the competition. We also welcome the submission of termination and complexity problems, especially problems that come from applications. A category is only run in the competition if there are at least 2 participants and at least 40 examples for this category in the underlying termination problem data base. If there is no category that is convenient for your tool, you can contact the organizers, since other categories can be considered as well if enough participants are guaranteed.
