To submit a paper, you are requested to register yourself and provide some information about the paper and authors. You may just register and submit only an abstract in the first phase. PDF or Postscript file can be uploaded later. Until the deadline, you can still update your information or transmit a revised file.

If you have already registered for another conference in EasyChair system after January 9, 2007, you can use the same username and password. You could easily switch among conferences.

An e-mail will be sent to you to confirm the receipt of your submission within 24 hours. If you have any problems/questions on submissions, please contact Jan Holub (

The extended abstract should provide sufficient details to allow the Program Committee to evaluate its validity, quality, and relevance to the conference. The extended abstract should be at most ten (10) pages long using 11-point font with ample margins. If appropriate, proof details omitted in the paper may be added in an appendix.

Authors will be notified of acceptance or rejection by May 10, 2007.

Final copies of accepted papers must be submitted by June 1, 2007 for publication in preproceedings published by Publishing House of Czech Technical University in Prague.

Later a deadline for submission of final copies for publication in a Springer-Verlag Lecture Notes in Computer Science Proceedings will be announced. (See, for example, LNCS 3845 and LNCS 4094 for the proceedings of two previous conferences.)

LNCS, Springer

Final version of accepted paper for both preproceedings and LNCS proceedings should be prepared using llncs.cls LaTeX style. Read carefully Springer's instructions on preparing the manuscript before you submit the final version. We request that you use the llncs.cls style file, which is contained in the package (Using other styles might delay the publication process.)

Extended versions of selected papers from the proceedings of the conference series will be solicited for publication in a special issue of Theoretical Computer Science (TCS) and International Journal of Foundations of Computer Science (IJFCS), alternating each year with the CIAA 2007 special issue appearing in TCS.

There will be a Best Paper Award for CIAA. The award is sponsored by the University of California at Santa Barbara.
