摘要
Given is a set S of n points, each colored with one of k >= 3 colours. We say that a triangle defined by three points of S is 3-colored if its vertices have distinct colours. We prove in this paper that the problem of constructing the boundary of the union T(S) of all such 3-colored triangles can be done in optimal O(n log n) time.
