Question: Given a sorted array keys [0.. n-1] of search keys and an array freq [0.. n-1] of frequency counts, where freq [i] is the number of searches to keys [i].
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 … WebThe time required to search a node in BST is more than the balanced binary search tree as a balanced binary search tree contains a lesser number of levels than the BST. There is one …
WebIn practice, key searches occur with di erent frequencies, and an Optimal Binary Search Tree tries to exploit this non-uniformity of access patterns, and has the following formalization. The input is a list of keys (words) w 1;w 2;:::;w n, along with their access probabilities p 1;p 2;:::;p n. The prob. are known at the start and do not change.
