Optimal binary search trees
WebA Binary Search Tree (BST) is a tree where the key values are stored in the internal nodes. The external nodes are null nodes. The keys are ordered lexicographically, i.e. for each … WebComputer Science. WADS. 2009. TLDR. A new linear-time algorithm for constructing multiway search trees with near-optimal search cost whose running time is independent of the size of the node in the tree and is able to provide the tightest upper bound on the average search cost for an optimal binary search tree. 8.
