Call For Papers


First Call for Papers -- DCFS 2013

15th International Workshop on Descriptional Complexity of Formal Systems

London, Ontario, Canada

July 22-25, 2013


DCFS 2013 will be held in London, Ontario, Canada, on July 22-25, 2013.
It will be preceded by CIAA in Halifax, Canada, 16-19 July.

Detailed information will be available at

The DCFS email address is:

Paper submissions are invited which fit into the general theme of the workshop.
In particular, we look for submissions in the following general areas -- this
list is not meant to be exclusive:

- Automata, grammars, languages and other formal systems; various modes
of operations and complexity measures.

- Succinctness of description of objects, state-explosion-like phenomena.

- Circuit complexity of Boolean functions and related measures.

- Size complexity of formal systems.

- Structural complexity of formal systems.

- Trade-offs between computational models and mode of operation.

- Applications of formal systems -- for instance in software and
hardware testing, in dialogue systems,
in systems modeling or in modeling natural languages-- and their complexity

- Co-operating formal systems.

- Size or structural complexity of formal systems for modeling
natural languages.

- Complexity aspects related to the combinatorics of words.

- Descriptional complexity in resource-bounded or structure-bounded

- Structural complexity as related to descriptional complexity.

- Frontiers between decidability and undecidability.

- Universality and reversibility.

- Nature-motivated (bio-inspired) architectures and unconventional models
of computing.

- Kolmogorov-Chaitin complexity, algorithmic information.

If in doubt, please feel free to ask for advice at the email address given above.

We invite original contributions to the field, but also look for exploratory expositions and
demonstrations of implementations.
The exact format of the workshop is still being discussed. Greater detail will be provided
both on the web site and the second call.


Papers presenting original contributions concerning the topics of the conference are being
sought. Authors are invited to submit papers of no more than 12 pages
in LNCS-style LaTeX2e (available at Papers must be in
English and provide sufficient details to allow the program committee
to assess their merits. Proofs omitted due to space constraints must
be put into an appendix to be read by the program committee members at
their discretion. Simultaneous submission to other conferences or
workshops with published proceedings is not allowed.

Papers will be submitted electronically in PDF, using the EasyChair system. Use
the following link for submission:

The proceedings will be published in the Springer Lecture Notes in
Computer Science (LNCS) series and will be available at the
workshop. As in previous years, a special journal issue with full
versions of selected papers will be devoted to DCFS 2013.

Submission Deadline: March 20, 2013
