System on TPTP
This interface is for solving problems. If you want to prepare problems, use the SystemB4TPTP interface. If you want to process solutions, use the SystemOnTSTP interface.

Solve the Problem System Recommendations and Reports
Solution attempts are limited to a few users at a time (until I get more resources - see the note at the top of the page). Your job may be rejected if the computers are too busy.
Override password: 		The recommendations and reports are based on the systems' results for the TPTP. There is no guarantee that they are right for your application. If no problem is specified then all possibilities will be used.

Our server does not output results until all tasks are completed. Be patient while the systems do their thing. Results are presented using the SZS problem status ontology.
