Optimal binary identification procedures
WebApr 12, 2024 · An Optimal Binary Search Tree (OBST), also known as a Weighted Binary Search Tree, is a binary search tree that minimizes the expected search cost. In a binary search tree, the search cost is the number of comparisons required to search for a given key. In an OBST, each node is assigned a weight that represents the probability of the key … WebSep 12, 2024 · Here is the example I'm trying to apply the optimal BST to: Let us define e [i,j] as the expected cost of searching an optimal binary search tree containing the keys labeled from i to j. Ultimately, we wish to compute e [1, n], where n is the number of keys (5 in this example). The final recursive formulation is:
