The article AbYSS: Adapting Scatter Search to Multiobjective Optimization has been published in IEEE Transactions on Evolutionary Computation, Volume 12 Issue 4 2008. It is a joint contribution of Antonio Nebro, Francisco Luna, Enrique Alba, Bernabé Dorronsoro, Juan Durillo from the University of Málaga and our Andreas Beham. The reference can be found, e.g. on the publication page.
Our colleague Gabriel Kronberger is currently in Hamburg, Germany, to present the paper "On the Effects of Enhanced Selection Models on Quality and Comparability of Classifiers Produced by Genetic Programming" at the 32nd Annual Conference of the German Classification Society (GfKl 2008).
Stephan Winkler attended the Genetic and Evolutionary Computation Conference (GECCO 2008) in Atlanta, Georgia, this week to present his contribution Fine-Grained Population Diversity Estimation for Genetic Programming Based Structure Identification (which is available as poster [pdf, 3.2 MB]).
