摘要：Following publication of the original article [1], in the description of the leaf shrinking procedure as well as in Algorithm 1 and the definition of edge-based graphs in [1], the condition that G contains at least two leaves (i.e., the condition |VL(G)| ≥ 2) needs to be omitted. Moreover, in line 2 of Algorithm 1 it should read jV ðLSðGÞÞj > 2.
