Abstract
SystemOnTPTP is a WWW interface that allows an ATP problem to be easily and quickly submitted in various ways to a range of ATP systems. The interface uses a suite of currently available ATP systems. The interface allows the problem to be selected from the TPTP library or for a problem written in TPTP syntax to be provided by the user. The problem may be submitted to one or more of the ATP systems in sequence, or may be submitted via the SSCPA interface to multiple systems in parallel. SystemOnTPTP also can provide system recommendations for a problem.
