SECOND CALL FOR PAPERS
(We apologize for cross postings)
Application of Hybrid Evolutionary Algorithms to NP-complete
Bird-of-a-feather GECCO-2003 Workshop
as part of the
Genetic and Evolutionary Computation Conference (GECCO-2003)
Chicago, July 12-16, 2003
Aims and Scope
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
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
algorithms and classical methods might improve the efficiency of search.
current approaches as a starting point, this workshop aims to promote a
about this topic and, most important, to analyze if it is possible to
develop new hybrid
architectures that perform better than todays methods.
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
· 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 todays 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
