The CADE ATP System Competition ... part of ... The 27th International Conference on Automated Deduction Natal, Brazil, 25th-30th August 2019

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-27 will be held on 29th August 2019, during the 27th International Conference on Automated Deduction (CADE-27).

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;

• 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-27 by Josef Urban (LTB division). The competition is overseen by a panel of knowledgeable researchers who are not participating in the event. The panel members are Aart Middeldorp, Christoph Weidenbach, and Uwe Waldmann. If you have any questions about the competition, please email the organizer.
