WebJul 1, 2004 · Both algorithms find the optimum usually several times faster than any other known Branch & Bound algorithm. As the algorithm computational efficiency is crucial, due to the exponential nature of the search problem, we also investigate other factors that affect the search performance of all Branch & Bound algorithms. WebNov 30, 1997 · The optimal binary search tree problem is to construct an optimal binary search tree given the keys and their access probabilities. A simple dynamic programming algorithm requiring 0 () time and 0 (n2) space was given by Gilbert and Moore [48] for the special case when only the 's are zero.

In computer science, an optimal binary search tree (Optimal BST), sometimes called a weight-balanced binary tree, is a binary search tree which provides the smallest possible search time (or expected search time) for a given sequence of accesses (or access probabilities). Optimal BSTs are generally divided into two … See more Definition In the static optimality problem as defined by Knuth, we are given a set of n ordered elements and a set of $${\displaystyle 2n+1}$$ probabilities.
