英文摘要: The rapid development of information technology leads to many new scientific problems, many of which can be modelled as optimization problems. This project studies mathematical properties of those optimization problems arisen in some selected important real problems in other scientific fields such as computer science, information technology and computational biology. The main tasks of the project will be the construction of efficient numerical methods for such optimization problems, the theoretical analysis, implementation and numerical experiments of these methods. Problems such as the optimal resouce allocation in wireless communication, various matrix optimization problems such as low-rank matrix completion and non-negative matrix factorization, data mining, and network optimization problems from wireless communication will be the main focus of this project. We hope to invent efficient methods for these special optimization problems, give theoretical properties of the new methods and test them in some real applications. This project will strengthen optimization research and promote the applications of optimization techniques in China.
