Apr 6, 2015 - The goal is to compute f(x), while minimizing the number of queries made to the black box. For a function f : {0,1}n → {0,1}, let D(f) denote the deterministic query complexity (or decision tree complexity) of computing f, the minimum

Dec 28, 2017 - Abstract. String matching is one of the most fundamental problems in computer science. A natural problem is to find the number of characters that needs to be queried (i.e. the decision tree complexity) in a string in order to determine

Nov 16, 2016 - decision tree is because of its simplicity and easy interpretability as a classification rule. In a decision tree classifier, each non-leaf node is associated with a so called split rule or a decision function which is a function of th
