Summary

Binary search trees are used in medical diagnostic, species identification, computer decision making, coding, sorting, etc. They are built by applying a sequence of binary tests, when it is required to identify some unknown object or condition, belonging to a given set of possibilities. We search to minimize the path length of a binary tree, giving the probabilities of events. We propose an algorithm which builds the binary tree from the root to the terminal vertices. In this paper, we point out the different properties of that algorithm and the conditions on the probability distribution so that the algorithm becomes nearly optimal.
