Efficient Construction of Balanced Binary Trees

D. J. Evans * and F. Abdollahzadeh *

Department of Computer Studies, Loughborough University of Technology, Loughborough, UK

An improved algorithm for balancing arithmetic expression trees is presented and its efficiency considered. When binary trees are constructed to represent arithmetic expressions and vacant nodes occur then by making use of the vacancy in the tree we are able to insert a smaller tree of lower height resulting in a balanced binary tree (b.b.t.) which is more efficient than those given by existing methods.


Received August 1981.
