Welcome to visit Chung-Shou Liao’s lab website! Our research mainly focuses on designing efficient combinatorial algorithms that can be used to solve hard optimization problems from real applications. The current research topics we investigate center around network and location problems related primarily to biological networks, transportation networks, power utility networks, logistics, and social networking. In particular, we put more attention on dynamic and online algorithms for the fundamental problems such as data clustering and classification in recent years. Other areas of interest include computational geometry, graph theory, and machine learning.
