This book - in conjunction with the two volumes LNCS LNAI 4681 and 4682 - is the referee of the Third International Conference on Intelligent Computing, ICIC 2007, held in Qingdao, China in August 2007. Intelligent computing technology includes a variety of techniques such as artificial intelligence informatics theory, perception and pattern recognition, evolutionary and adaptive computing, and applications, computational neuroscience and bioscience, soft computing, case-based and limited reasoning, agent, network and computer supported co-operative work, computer human interface problems. ICIC brings together the theme of the picture of contemporary intelligent computing techniques as an integral concept that highlights the trends in advanced computational intelligence and bridges theoretical research with applications.
