The CADE conferences are the major forum 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 conference. CASC-J4 will be held at the 4th International Joint Conference on Automated Reasoning (IJCAR, which incorporates CADE), on 13th August 2008.

CASC evaluates the performance of sound, fully automatic, classical 1st order ATP systems. The evaluation is in terms of:

• the number of problems solved, and
• 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. The competition is overseen by a panel of knowledgeable researchers who are not participating in the event. The panel members are Alessandro Armando, Christoph Benzmüller, and John Slaney, If you have any questions about the competition, please email the organizers.
