内容記述タイプ Abstract
内容記述 Problems of realizing a vertex-weighted tree with a given weighted tranamission number sequence are discussed in this paper. First we consider properties of the weighted transmission number sequence of a vertex-weighted tree. Let S be a sequence whose terms are pairs of a non-negative integer and a positive integer. The problem determining whether S is the weighted transmission number sequence of a vertex-weighted tree or not, is called w-TNS. We prove that w-TNS is NP-complete, and we show an algorithm using backtracking. This algorithm always gives a correct solution. And, if each transmission number of S is different to the others, then the time complexity of this is only 0( ∣ S ∣ 2).Next we consider the d2-transmission number sequence so that the distance function is defined by a special convex function.
