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
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.
