Call for papers: Special Issue of DAM

Following the tradition of previous workshops, a special issue of Discrete Applied Mathematics will be devoted to the 10th edition of Cologne-Twente Workshop on Graphs and Combinatorial Optimization. All interested researchers are invited to contribute to this special volume. The topics should relate to the themes of the workshop (graphs, combinatorial optimization and the design and analysis of algorithms).

• Submissions of contributions not presented at the workshop are welcome.
• All articles will be thoroughly refereed according to the high standards of Discrete Applied Mathematics.
• Submission deadline is *November 30, 2011*. However, extensions of the deadline may be obtained upon request, if necessary.
• The full papers must be submitted through the Elsevier Editorial System (http://ees.elsevier.com/dam). When submitting your paper, be sure to specify that the paper is a contribution for the Special Issue of CTW 2011, so that your paper is assigned to the guest editors.
