Abstract (in Japanese) (See Japanese page) 
(in English) A random walk on a finite graph is a model that a token on a vertex repeatedly moves to an adjacent vertex randomly chosen according to some transition probability. The cover time of a random walk is a criterion of its speed, and roughly speaking, it is the expected number of steps in which the token visits all the vertices. Given a graph, we consider to design a fast random walk in terms of the cover time, by properly setting the transition probability. In this paper, we give necessary conditions for that the given graph has the cover time of O(n), where n is the number of vertices.
