Noisy Generalized Binary Search
This paper addresses the problem of noisy Generalized Binary Search (GBS). GBS is a well-known greedy algorithm for determining a binary-valued hypothesis through a sequence of strategically selected queries. At each step, a query is selected that most evenly splits the hypotheses under consideration into two disjoint subsets, a natural generalization of the idea underlying classic binary searc...
متن کاملThe geometry of binary search trees
We present a novel connection between binary search trees (BSTs) and points in the plane satisfying a simple property. Using this correspondence, we achieve the following results: 1. A surprisingly clean restatement in geometric terms of many results and conjectures relating to BSTs and dynamic optimality. 2. A new lower bound for searching in the BST model, which subsumes the previous two know...
متن کاملGeneralized Binary Search For Split-Neighborly Problems
In sequential hypothesis testing, Generalized Binary Search (GBS) greedily chooses the test with the highest information gain at each step. It is known that GBS obtains the gold standard query cost of O(log n) for problems satisfying the k-neighborly condition, which requires any two tests to be connected by a sequence of tests where neighboring tests disagree on at most k hypotheses. In this p...
متن کاملProfile and Height of Random Binary Search Trees
The purpose of this article is to survey recent results on distributional properties of random binary search trees. In particular we consider the profile and the height.
متن کاملModified Group Generalized Binary Search with Near-Optimal Performance Guarantees
Group Generalized Binary Search (Group GBS) is an extension of the well known greedy algorithm GBS, for identifying the group of an unknown object while minimizing the number of binary questions posed about that object. This problem referred to as group identification or the Equivalence Class determination problem arises in applications such as disease diagnosis, toxic chemical identification, ...
