A new algorithm, CONVEX, that determines which points of a planar set are vertices of the
convex hull of the set is presented. It is shown that CONVEX operates in a fashion similar to
the sorting algorithm QUICKERSORT. Evidence is given which indicates that in some
situations CONVEX is preferable to earlier algorithms. A Fortran implementation, intended to
minimize execution time, is presented and an alternative, which minimizes storage
requirements, is discussed.
