A binary split tree is a search structure combining features of heaps and binary search trees. Building an optimal binary split tree was originally conjectured to be intractable due to di culties in applying dynamic programming techniques to the problem. However, two algorithms have recently been published which generate optimal trees in O(n5) time, for records with distinct access probabilitie...
