Abstract

In this paper, we present an O(n2) time algorithm to find a largest area triangle contained inside a terrain with n vertices. We also present an O(nlog⁡n) time [Formula presented]-factor approximation algorithm and an [Formula presented] time (1−ε)-factor approximation scheme for the same.
