Optimal binary search trees problems
WebTo construct a binary search tree, we have to determine if the key already exists in the BST or not for each given key. The cost of finding a BST key is equal to the level of the key (if present in the BST). Output: The optimal cost of constructing BST is 95. 25 lookups of the key 0 will cost 1 each. 20 lookups of the key 2 will cost 2 each. WebDefinition (Optimal Binary Search Tree (OBST) Problem) The optimal binary search tree (OBST) problem is given an ordered set of keys and a probability function : where is the set of all BSTs on , and is the depth of the key in the tree (the root has depth 1).

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 internal node all the keys in the left sub-tree are less than the keys in the node, and all the keys in the right sub-tree are greater.
