23-24 September 2017, Brasilia, Brazil
The PxTP workshop brings together researchers working on various aspects of communication, integration, and cooperation between reasoning systems and formalisms.
The progress in computer-aided reasoning, both automated and interactive, during the past decades, made it possible to build deduction tools that are increasingly more applicable to a wider range of problems and are able to tackle larger problems progressively faster. In recent years, cooperation of such tools in larger verification environments has demonstrated the potential to reduce the amount of manual intervention. Examples include the Sledgehammer tool providing an interface between Isabelle and (untrusted) automated provers, and also collaboration between HOL Light and Isabelle in the formal proof of the Kepler conjecture.
Cooperation between reasoning systems relies on availability of theoretical formalisms and practical tools to exchange problems, proofs, and models. The PxTP workshop strives to encourage such cooperation by inviting contributions on suitable integration, translation and communication methods, standards, protocols, and programming interfaces. The workshop welcomes the interested developers of automated and interactive theorem proving tools, developers of combined systems, developers and users of translation tools and interfaces, and producers of standards and protocols. We are also interested both in success stories and in descriptions of the current bottlenecks and proposals for improvement.
Topics of interest for this workshop include all aspects of cooperation between reasoning tools, whether automatic or interactive. More specifically, some suggested topics are:
Researchers interested in participating are invited to submit either an extended abstract (up to 8 pages) or a regular paper (up to 15 pages). Submissions will be refereed by the program committee, which will select a balanced program of high-quality contributions. Short submissions that could stimulate fruitful discussion at the workshop are particularly welcome. We expect that one author of every accepted paper will present their work at the workshop.
Submitted papers should describe previously unpublished work, and must be prepared using the LaTeX EPTCS class. Papers should be submitted via EasyChair, at the PxTP'2017 workshop page. Accepted regular papers will appear in an EPTCS volume.
Registration to PxTP is part of the Tableaux/FroCoS/ITP registration process.
