Message from General Co-chairs and Program Co-chairs

Computational Sciences and Optimization are two important disciplines in modern sciences with many applications ranging from applied sciences, engineering, management, finance, and economics, to arts, humanities, and social sciences. Currently some new challenges arise in the modeling of complex systems, sophisticated algorithms, advanced scientific and engineering computing and associated problem-solving environments. Because the solutions of complex problems must cope with the tight timing schedule, powerful computational algorithms and complex optimization techniques are inevitable for solving these practical problems. In order to strengthen academic exchanges and discussions on the fields of computational sciences and optimization, The Fifth International Joint Conference on Computational Sciences and Optimization (CSO 2012) will be held on June 24-26, 2012 in Harbin, Heilongjiang Province, China. It provides a three-day forum on Computational Sciences and Optimization. CSO 2012 received 648 submissions (including main track papers and workshop papers) from different countries and regions. All submitted papers have to go through a rigorous reviewing process. Each submission was reviewed by at least two independent reviewers in a standard peer-review process. Papers belonged to three categories: regular papers of 5 pages, short papers of 4 pages and poster papers of 2 pages. After rigorous peer-review, we finally selected 203 papers (acceptance rate 31.33%) for publication. It should be emphasized that our policy is to guarantee the high-quality of the accepted papers and at the same time encourage more people to participate in the conference.
