Computational Intelligence and Intelligent Systems: 4th International Symposium on Intelligence Computation and Applications, Isica 2009, Huangshi, China, October 23-25, 2009

VolumesofLNCS 5821andCCIS51aretheproceedingsofthe 4thInternational Symposium on Intelligence Computation and Applications (ISICA 2009) held in Huangshi, China, October 23-25, 2009. These two volumes are in memory of Prof. Lishan Kang, the ISICA 2009 Honorary General Chair, who was a leading ?gurein the ?elds of domain decomposition methods and computational intelligence. ISICA 2009 successfully attracted over 300 submissions. Through rigorous reviews, 58 high-quality papers were included in LNCS 5821, while the other 54 papers were collected in CCIS 51. ISICA conferencesare one of the ?rst series of internationalconferencesoncomputationalintelligencethatcombineelementsof learning, adaptation, evolution and fuzzy logic to create programsas alternative solutions to arti?cial intelligence. The last three ISICA proceedings have been accepted in the Index to Scienti?c and Technical Proceedings (ISTP) and/or Engineering Information (EI). Following the success of the past three ISICA events, ISICA 2009 made good progress in the analysis and design of newly developed methods in the ?eld of computationalintelligence. ISICA 2009featured the most up-to-dateresearchin analysisandtheoryofevolutionaryalgorithms,neuralnetworkarchitecturesand learning, fuzzy logic and control, predictive modeling for robust classi?cation, swarm intelligence, evolutionary system design, evolutionary image analysis and signal processing, and computational intelligence in engineering design. ISICA 2009 provided a venue to foster technical exchanges, renew everlasting frie- ships, and establish new connections.
