This paper presents a theorem that asserts that average edge length of the
minimum spanning tree of a complete graph on n + 1 vertices is less than or
equal to the average edge length of all the n + 1 minimum spanning trees o
f the induced graph on n vertices. The result is also in compliance with re
sults given by Frieze and Steele. (C) 1999 Elsevier Science B.V. All rights
