### Abstract

Suppose each edge of the complete graph K_{n} is assigned a random weight chosen independently and uniformly from the unit interval [0,1]. A minimal spanning tree is a spanning tree of K_{n} with the minimum weight. It is easy to show that such a tree is unique almost surely. This paper concerns the number N_{n}(α) of vertices of degree α in the minimal spanning tree of K_{n}. For a positive integer α, Aldous (Random Struct. Algorithms 1 (1990) 383) proved that the expectation of N_{n}(α) is asymptotically γ(α)n, where γ(α) is a function of α given by explicit integrations. We develop an algorithm to generate the minimal spanning tree and Chernoff-type tail bound for N_{n}(α).
