                                          CALL FOR PAPERS
                                      (We apologize for cross postings)

                        Application of Hybrid Evolutionary Algorithms to NP-complete Problems

                                    Bird-of-a-feather GECCO-2003 Workshop
                                                   as part of the
                        Genetic and Evolutionary Computation Conference (GECCO-2003)
                                 Chicago, July 12-16 (Saturday-Wednesday), 2003

      This workshop will focus on the application of hybrid Evolutionary Computation (EC)
      techniques to NP-complete problems. There are many examples of problems belonging to
      this class, such as the boolean satisfiability (SAT), clique, decision trees, graph
      partitioning or Hamiltonian circuits. Moreover, optimization problems belonging to
      the NP-hard complexity class, such as the traveling salesperson or bin packing can
      easily be restated in terms of a decision version. As an example, the optimization
      question "What is the shortest tour?" which is NP-hard, can be restated as the NP-complete
      decision problem "Is there a tour length less than K?".
      When applied to this class of problems, evolutionary techniques can benefit from
      hybridizing with problem-specific algorithms. In the past few years, results obtained
      by several investigations give a clear indication that the joint application of
      stochastic optimization algorithms and classical methods might improve the efficiency
      of search. Adopting several current approaches as a starting point, this workshop aims
      to promote a widespread discussion about this topic and, most important, to analyze if
      it is possible to develop new hybrid architectures that perform better than today's

      Topics of interest
      The workshop considers hybridization in a general sense. Topics of interest include,
      but are not restricted to:
      * Hybridization with exact techniques, such as the branch and bound, dynamic programming
        or linear programming.
      * Hybridization with approximation algorithms, i.e., methods that provide a guarantee
        on the quality of the solutions obtained.
      * Using EC algorithms inside exact techniques.
      * Analysis of the strengths (and weaknesses) of today's EC-based approaches. Studies
         of how they compare to other techniques that are also applied in these problems.
      * Studies for which kind of NP-complete problems, hybrid EC algorithms are particularly
         well suited.

      Submission procedure
      We invite submissions reporting work in the area of the workshop. Send your manuscript
      (postscript or PFD) via e-mail to xico@..., no later than February 24, 2003.
      Submissions should follow the layout guidelines given for the main GECCO-2003
      conference (formatting instructions can be found here: http://www-illigal.ge.uiuc.edu:8080/GECCO-2003/submissions.html)
      and must not exceed 8 pages.
      All the submissions will be fully refereed. Authors will be notified via e-mail on
      the results of the review by March 12, 2003. Accepted papers will be orally presented
      during the workshop and will be included in the GECCO-2003 Workshop Proceedings.
      Authors of accepted papers will have to improve their paper on the basis of the
      reviewers' comments and will be asked to send a camera-ready version of their manuscripts
      by April 4, 2003.

      Important Dates
      February 24, 2003: Submission deadline
      March 12, 2003: Notification of acceptance

      The workshop is open to all registered members of GECCO-2003.
      By submitting a camera-ready paper, the author agrees that she/he will attend the
      workshop and present the accepted paper at the workshop.
