The partitions of a natural number n (with parts taken in non-increasing order), may be listed in dictionary order. This ordering of partitions is shown to correspond to the post ordering of chains of a finite tree T[n]. It is shown that T[n] belongs to a, the class of normal trees. % occurs indepen

โฆ Synopsis
For a fixed positive integer k, the k-path partition problem is to partition the vertex set of a graph into the smallest number of paths such that each path has at most k vertices. The 2path partition problem is equivalent to the edge-cover problem. This paper presents a linear-time algorithm for the k-path partition problem in trees. The algorithm is applicable to the problem of finding the minimum number of message originators necessary to broadcast a message to all vertices in a tree network in one or two time units.
