Research Abstract

One of the main challenge in modern algorithm design is to copewith insufficient information. In this study, we try to construct a general framework fordesign and evaluation of algorithms that can cope with insufficient spatial information. Asa result, we give design and analysis of such algorithms for various problems in severalfields such as graph problems, algorithmic game theory and randomized computationtheory.
