The deadline for draft paper submission at the 2009 International Conference on Artificial Intelligence and Pattern Recognition (AIPR-09) (website: http://www.PromoteResearch.org) is extended due to numerous requests from the authors. As a result, the deadline for paper submission for the special session on Evolutionary Computing is also extended accordingly. The conference and the session will be held during July 13-16 2009 in Orlando, FL, USA. We invite draft paper submissions. The conference will take place at the same time and venue where several other international conferences are taking place. The other conferences include: ????????? International Conference on Automation, Robotics and Control Systems (ARCS-09) ????????? International Conference on Bioinformatics, Computational Biology, Genomics and Chemoinformatics (BCBGC-09) ????????? International Conference on Enterprise Information Systems and Web Technologies (EISWT-09) ????????? International Conference on High Performance Computing, Networking and Communication Systems (HPCNCS-09) ????????? International Conference on Information Security and Privacy (ISP-09) ????????? International Conference on Recent Advances in Information Technology and Applications (RAITA-09) ????????? International Conference on Software Engineering Theory and Practice (SETP-09) ????????? International Conference on Theory and Applications of Computational Science (TACS-09) ????????? International Conference on Theoretical and Mathematical Foundations of Computer Science (TMFCS-09) ?

Got a project on this but dont know how to start off. Thank you! -------------- next part -------------- An HTML attachment was scrubbed...

I found some theoretical treatments of reordering operators in the literature, but not much in the way of real-life success stories. Thanks.

I played with reordering crossover a bit but found that in practice it doesn't perform nearly as well as edge recombination. I didn't do any formal study of that component of my implementation, but if you're looking for anecdotal data there it is.
