WebMar 22, 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 … WebAn Optimal Binary Search Tree is the one for which the average number of comparisons in a search is the smallest possible, if the probability of searching each elements is given.

WebThat BST would be one with the lowest total lookup cost, where that cost is calculated using the approach you worked through earlier on. The terminology for a BST with that property - that it has the best lookup speed for those frequencies among all the possible BSTs that you can make - is an optimal BST.
