WebCS 466 Optimal Binary Search Trees Slide 3-2 Optimal Binary Search Trees Try a few top down heuristics, and we easily get non-optimal trees. We need some definitions: k i: ith largest of key value i=1..n d i: dummy leaf after k i,before k i+1 i=0..n p i: probability of a request for k i q i: probability of a request for an element after p i and ... WebSummary. We discuss two simple strategies for constructing binary search trees: “Place the most frequently occurring name at the root of the tree, then proceed similary on the subtrees “and” choose the root so as to equalize the total weight of the left and right subtrees as much as possible, then proceed similarly on the subtres.”.

Knuth Computer Science Acta Informatica 2004 TLDR To find if a given name is in the tree, the authors compare it to the name at the root, and four cases arise: 1. There is no root (the binary tree is empty), 2. The given name matches theName at theRoot: The search terminates suecess/ully, 3.
