Popis: We present two efficient algorithms constructing a spanning tree with minimum eccentricity of a source, for a given graph with weighted edges and a set of source vertices. The first algorithm is both simpler to implement and faster of the two. The second approach involves enumerating single-source shortest-path spanning trees for all points on a graph, a technique that may be useful in solving other problems.
