Welcome to FroCoS 2017 in Brasília!

The 11th International Symposium on Frontiers of Combining Systems will take place in Brasília - the garden city of Brazil and UNESCO World Heritage Site for its modernistic design. It will be hosted by the Department of Computer Science at the University of Brasília, from 27-29 September 2017.

FroCoS is the main international event for research on the development of techniques and methods for the combination and integration of formal systems, their modularization and analysis. The first FroCoS symposium was held in Munich, Germany, in 1996. Initially held every two years, since 2004 it has been organised annually with alternate years forming part of IJCAR.

FroCoS 2017 will be co-located with the 26th International Conference on Automated Reasoning with Analytic Tableaux and Related Methods (Tableaux 2017) and the 8th International Conference on Interactive Theorem Proving (ITP 2017).

The FroCoS 2017 conference will be published in the Springer series Lecture Notes in Artificial Intelligence (LNAI).

Scope:

In various areas of computer science, such as logic, computation, program development and verification, artificial intelligence, knowledge representation, and automated reasoning, there is an obvious need for using specialized formalisms and inference systems for selected tasks. To be usable in practice, these specialized systems must be combined with each other and integrated into general purpose systems. This has led – in many research areas – to the development of techniques and methods for the combination and integration of dedicated formal systems, as well as for their modularization and analysis.

The International Symposium on Frontiers of Combining Systems (FroCoS) traditionally focuses on these types of research questions and activities. Like its predecessors, FroCoS 2017 seeks to offer a common forum for research in the general area of combination, modularization, and integration of systems, with emphasis on logic-based ones, and of their practical use.

Topics:

Topics of interest for FroCoS'17 include (but are not restricted to):

  • combinations of logics (such as higher-order, first-order, temporal, modal, description or other non-classical logics);
  • combination and integration methods in SAT and SMT solving;
  • combination of decision procedures, satisfiability procedures, constraint solving techniques, or logical frameworks;
  • combination of logics with probability and/or fuzzy measures;
  • combinations and modularity in ontologies;
  • integration of equational and other theories into deductive systems;
  • hybrid methods for deduction, resolution and constraint propagation;
  • hybrid systems in knowledge representation and natural language semantics;
  • combined logics for distributed and multi-agent systems;
  • logical aspects of combining and modularizing programs and specifications;
  • integration of data structures into constraint logic programming and deduction;
  • combinations and modularity in term rewriting;
  • applications of methods and techniques to the verification and analysis of information systems.

    Title: Foundational (Co)datatypes and (Co)recursion for Isabelle/HOL
    Joint work with Julian Biendarra, Aymeric Bouzy, Martin Desharnais, Mathias Fleury, Johannes Hölzl, Ondřej Kunčar, Andreas Lochbihler, Fabian Meier, Lorenz Panny, Andrei Popescu, Christian Sternagel, René Thiemann, and Dmitriy Traytel

    Abstract: Systems such as Isabelle adhere to the tradition initiated in the 1970s by the LCF system: All inferences are derived by a small trusted kernel; types and functions are defined rather than axiomatized to guard against inconsistencies. In this talk, I will describe a line of work that started in 2011 towards enriching Isabelle/HOL's language with coalgebraic datatypes (which allow infinite values) and with a more expressive notion of algebraic datatypes. These new (co)datatypes are complemented by definitional principles for (co)recursive functions and reasoning principles for (co)induction. In contrast with Agda, Coq, Lean, and Matita, no additional axioms or logic extensions are necessary.

    Paper submission:

    The program committee seeks high-quality submissions describing original work, written in English, not overlapping with published or simultaneously submitted work to a journal or conference with archival proceedings. Selection criteria include accuracy and originality of ideas, clarity and significance of results, and quality of presentation. The page limit in Springer LNCS style is 16 pages in total, including references and figures.

    Papers must be edited in LaTeX using the llncs style and must be submitted electronically as PDF files via the EasyChair system at

    https://easychair.org/conferences/?conf=frocos2017.

    For each accepted paper, at least one of the authors is required to attend the symposium and present the work. Prospective authors must register a title and an abstract five days before the paper submission deadline.

    Formatting instructions and the LNCS style files can be obtained at:

    Call for Workshop/Tutorials:

    Following the long tradition of TABLEAUX, FroCoS, and ITP, we invite researchers and practitioners to submit proposals for co-located workshops and in-depth tutorials on topics relating to automated theorem proving and its applications. Workshops/tutorials can target the automated reasoning community in general, focus on a particular theorem proving system, or highlight more specific issues or recent developments.

    Co-located events will take place between 23 and 24/25 September and will be held on the same premises as the main conference. Conference facilities are offered free of charge to the organisers. Workshop/tutorial-only attendees will enjoy a significantly reduced registration fee.

    Detailed organisational matters such as paper submission and review process, or publication of proceedings, are up to the organisers of individual workshops. All accepted workshops/tutorials will be expected to have their program ready by 18 August 2017.

    Proposals for workshops/tutorials should contain at least the following pieces of information:

  • name and contact details of the main organiser(s)
  • (if applicable:) names of additional organisers
  • title and organisational style of event (tutorial, public workshop, project workshop, etc.)
  • preferred length of workshop (between half day and two days)
  • estimated number of attendees
  • short (up to one page) description of topic
  • (if applicable:) pointers to previous editions of the workshop, or to similar events
  • Proposals are invited to be submitted by email to nalon@unb.br, no later than 9 December 2016. Selected events will be notified by 23 December 2016. The workshop/tutorial selection committee consists of the TABLEAUX, FroCoS, and ITP program chairs and the conference organisers.
