Let G = (V, E) be a graph. The distance d (u, v) between two nodes u and v is the length of the shortest path between them. The eccentricity E (v) of a graph vertex v in connected graph G is the maximum distance between v and any other vertex u of G. i. e. maxu V{ d (u, v) }. The diameter of the graph is a graph the longest shortest path between any two graph vertices (u ,v) of a graph i. e. Diam (G) = max { E (v)/ v V}. The minimum eccentricity of a graph is radius i. e. Rad (G) = min { E (v)/ v V}. In this paper we propose algorithms for finding eccentricity diameter and radius of a tree using DFS.
