## Submission

Before submitting a file, please follow the guidelines given in Instructions for Authors. When your file is ready, please submit it through the START Conference Manager. The deadline for submissions is November 17, 2008.

The accepted extended abstract will be published in a proceedings volume of DMTCS (Discrete Mathematics and Theoretical Computer Science). The authors will retain the right of publishing a full version of their work in another journal. Authors who do intend to publish a full version elsewhere should however make sure that their conference contribution is clearly an extended abstract of this full version.

### Instructions for Authors:

In order to prepare your submission, please take the following steps to format your document according to the specifications of DMTCS (Discrete Mathematics and Theoretical Computer Science). Please prepare your document using standard LaTeX. If you have any user macros, please include them in your submission. We thank you very much for your cooperation.

2. To prepare your document, please follow the directions given in sample.tex . Submissions should be submitted as either postscript or pdf files. Please LaTeX the sample.tex to make sure that your output matches the corresponding sample.pdf file.
3. Fill in your author and institution information.
4. If your title is rather long, please give a short title substitution for the inside headers, e.g. \title[short title]{Long, wordy title} . The same goes for your name, if you have a preferred short form.
5. You must provide 3 to 6 keywords in the form \keywords{keyword1, keyword2, keyword3} that describe the topic of your paper.
6. Include a summary with citations written out rather than referencing the bibliography. FPSAC/SFCA has a tradition of encouraging bilingualism, and thus you are strongly encouraged to include a summary in the French language. There are people available to help you with this, if help is required. Please format your summary as follows ( Note the nested structure ):
\begin{abstract}
\paragraph{Abstract.}
text in english

\paragraph{R\'esum\'e.}
texte en francais

\end{abstract}

7. Submissions, when compiled using the dmtcs.cls class file, should not exceed 12 pages.
Papers should be submitted electronically.
