Dear Coq enthusiasts,

we are organizing another edition of the proving competition workshop "Proof Ground", which will take place virtually just before ITP 2021.

Please take note of our Call for Problems, and spread the word!

Call for Problems

Proof Ground 2021

Interactive Proving Contest

June 28, 2021

https://www21.in.tum.de/~wimmers/proofground/

at ITP 2021

Interactive Theorem Proving

June 29 - July 2, 2021, (originally in) Rome, Italy, now fully virtual

https://easyconferences.eu/itp2021/

This workshop brings together researchers of the ITP community to compete in a "proving contest".

While programming contests (e.g. ACM ICPC, International Olympiad in Informatics) challenge large numbers of participants to solve algorithmic problems within a short time, we envision proving contests to entice proof engineers to formally prove small but interesting problems from mathematics or computer science.

A contest system is currently used for teaching and hosting proving contests in Coq, Isabelle, and Lean.

Proof Ground 2021 is affiliated with the conference on Interactive Theorem Proving 2021.

As the main conference will happen as virtual conferences due to the ongoing Covid-19 pandemic, Proof Ground 2021 will also take a purely virtual format.

The first edition of the workshop has been held at ITP 2019. The second edition was affiliated with IJCAR 2020.

- Submission deadline: May 30, 2021
- Workshop and Competition: June 28, 2021

In order to conduct a stimulating contest we solicit interesting tasks.

A contest typically lasts for two hours and consists of around five

problems with varying difficulty.

A problem:

- should contain an informal statement of the problem together with a template for the formal proof;
- should come with a reference solution (in any ITP);
- should be solvable (including formal proof) within 30 minutes;
- should be easy to state in any proof assistant, without requiring too much background library;
- could be from any part of mathematics, software verification, or your daily work with ITPs, and could also be a logic puzzle/riddle;
- could contain several subproblems which lead to partial points.

Submissions from (potential) competition participants are allowed.

Examples can be found at the current "Proving for Fun" contest system, e.g. here.

Submissions can be made via email to wimmers [at] in [dot] tum [dot] de by the date indicated above.

@maximilian p.l. haslbeck You should probably send this announcement to coq-club@inria.fr and the Discourse forum (you can do so via e-mail if you prefer at coq+announcements@discoursemail.com) instead of here. All Discourse announcements are forwarded to the Announcements stream here on Zulip (which is otherwise read-only).
