Abstract
A method of using a binary tree data structure to represent a time-varying variable, and to solve queries about the variable. The tree is especially useful for solving “find” type queries, such as “What is the earliest/latest time when a minimum of y units are on hand?” This type of query can be solved with a efficiency of O(log n), where n is the number of nodes of the tree.
