Sklansky 1972

In 1972, Sklansky presented [1] the first algorithm for finding the convex hull of a simple polygon in linear time. It is an extremely simple procedure. Even though it is wrong, the main step is used in many algorithms to follow, so I suggest understanding it.

This link provides detailed information on Sklansky's algorithm: 3 Coins algorithm.
