WebDec 29, 2011 · There are many algorithms for finding optimal binary search trees given a set of keys and the associated probabilities of those keys being chosen. The binary search tree produced this way will have the lowest expected times to look up those elements. However, this binary search tree might not be optimal with regards to other measures.
