Method and system for finding a k order statistic in a union of sorted sets

摘要

A method for determining a k order statistic is provided. The method initiates with identifying at least two sorted sets. Then, a recurrence configured to eliminate elements of the at least two sorted sets is defined. Next, an index value associated with a k order statistic is reduced through the recurrence to obtain a base case. After obtaining the base case, a minimum value of remaining elements is selected from the at least two sorted sets. The minimum value corresponds to the k order statistic. A display controller having circuitry for determining a median value and a computer readable medium having program instructions for determining a k order statistic are also provided.
