The CADE ATP System Competition

... part of ...

The 28th International Conference on Automated Deduction
Online, Earth, 11th - 16th July 2021

The CADE and IJCAR conferences are the major forums for the presentation of new research in all aspects of automated deduction. In order to stimulate ATP research and system development, and to expose ATP systems within and beyond the ATP community, the CADE ATP System Competition (CASC) is held at each CADE and IJCAR conference. CASC-28 will be held on 13th July 2021, during the 28th International Conference on Automated Deduction (CADE-28).

CASC evaluates the performance of sound, fully automatic, ATP systems. The evaluation is in terms of:

the number of problems solved,
the number of problems solved with a solution output, and
the average runtime for problems solved;

in the context of:

a bounded number of eligible problems, chosen from the TPTP Problem Library, and
specified time limits on solution attempts.

The competition organizer is Geoff Sutcliffe, assisted in CASC-28 by Martin Desharnais (SLH and LTB divisions). The competition is overseen by a panel of knowledgeable researchers who are not participating in the event. The panel members are Peter Baumgartner, Pascal Fontaine, and Christoph Weidenbach. If you have any questions about the competition, please email the organizer.

Deadlines and Important Dates

Jasmin Blanchette at the Vrije Universiteit Amsterdam has contributed a travel prize for the Slammer Hammer (SLH) division. The prize is a four-night stay in Amsterdam, including one night in a romantic bridge house, to visit Jasmin's team at the university. The (European segments of) travel and the hotel expenses will be covered by the Matryoshka project. The prize must be redeemed before CASC-J11.
