Abstract

An algorithm for constructing dynamic convex hull of n points in the plane based on the new criteria for determination of vertex type and vertex position is presented. While this algorithm has O(log n) time for update and O(nlog n) time for the total processing as existing ones, the new criteria make it more compact, explicit and reasonable. In addition, it has the ability to deal with all special cases and therefore is more powerful.
