Welcome to the proceedings of the International Conference on Information ComputingandApplications(ICICA2010),whichwasheldinTangshan,China, October 15-18, 2010. As future-generation information technology, information computing and applications become specialized, information computing and applications - cluding hardware, software, communications and networks are growing with ever-increasing scale and heterogeneity and becoming overly complex. The c- plexity is gettingmore criticalalongwiththe growingapplications.Tocope with the growingandcomputing complexity,informationcomputing and applications focusonintelligent,selfmanageable,scalablecomputingsystemsandapplications to the maximum extent possible without human intervention or guidance. With the rapid development of information science and technology, infor- tion computing has become the third approach of science research. Information computing and applications is the ?eld of study concerned with constructing intelligent computing, mathematical models, numerical solution techniques and using computersto analyzeandsolvenaturalscienti?c,socialscienti?c anden- neeringproblems.Inpracticaluse,itistypicallytheapplicationofcomputers- ulation, intelligent computing, internet computing, pervasive computing, sc- ablecomputing,trustedcomputing,autonomy-orientedcomputing,evolutionary computing, mobile computing, applications and other forms of computation - dressing problems in various scienti? c disciplines and engineering. Information computing and applications is an important underpinning for techniques used in information and computational science and there are many unresolved problems worth studying. The ICICA 2010 conference provided a forum for engineers and scientists in academia, industry, and government to address the most innovative research and development including technical challenges and social, legal, political, and economic issues, and to present and discuss their ideas, results, work in progress and experience on all aspects of information computing and applications.
