CALL FOR PAPERS: Automated Deduction: Decidability, Complexity, Tractability, 10 June 2013, Lake Placid NY (U.S.A.)

ADDCT 2013

Workshop affiliated with CADE-24, Lake Placid, 10.06.2013

Important Dates
    8 April  2013: Paper submission (extended)
    30 April 2013: Notification
    10 May   2013: Final version
    10 June  2013: Workshop

Decidability, and especially complexity and tractability of logical
theories is extremely important for a large number of applications.
Although predicate logic and number theory are undecidable, decidable
theories or decidable theory fragments often occur in mathematics,
in program verification, in the verification of reactive, real time
or hybrid systems, as well as in databases and ontologies.

It is therefore important to identify such decidable fragments and to
design efficient decision procedures for them. It is equally important
to have uniform methods (e.g. resolution, rewriting, tableaux, sequent
calculi) which can be tuned to provide algorithms with optimal complexity.

The goal of ADDCT is to bring together researchers interested in
- identifying (fragments of) logical theories which are decidable,
   identifying fragments thereof which have low complexity, and
   analyzing possibilities of obtaining optimal complexity results
   with uniform tools;
- analyzing decidability in combinations of theories and possibilities
   of combining decision procedures;
- efficient implementations for decidable fragments;
- application domains where decidability resp. tractability are crucial.

Topics of interest for ADDCT include (but are not restricted to):

- Decidability:
    - decision procedures based on logical calculi such as:
      resolution, rewriting, tableaux, sequent calculi, or natural deduction
    - decidability in combinations of logical theories
- Complexity:
    - complexity analysis for fragments of first- (or higher) order logic
    - complexity analysis for combinations of logical theories
      (including parameterized complexity results)
- Tractability (in logic, automated reasoning, algebra, ...)

- Application domains for which complexity issues are essential
   (verification, security, databases, ontologies, ...)

The goal of ADDCT is to bring together researchers interested in exploring
the topics above, both at a theoretical level and motivated by applications.

Submissions are encouraged in one of the following categories:

- Original papers (up to 15 pages, LNCS style, including bibliography);
   should describe original research and contain sufficient detail to
   assess the merits and relevance of the contribution.
   Simultaneous submission of material is prohibited.

- Work in progress (up to 6 pages, LNCS style, without bibliography).

- Presentation-only papers: may describe work previously published,
   and will not be inserted in the proceedings. We are allowing the
   submission of previously published work in order to allow researchers
   to communicate good ideas that the attendees may not be aware of.

Given the informal style of the workshop, the submission of papers
presenting student's work and work in progress is encouraged.

Submission of papers is via EasyChair at

The final versions of the selected contributions will be collected in a
volume to be distributed at the workshop and made accessible on the web.
