WebSearch ACM Digital Library. Search Search. Advanced Search 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.
