Given in the plane a setSofmpoint sites in a simple polygonPofnvertices, we consider the problem of computing the geodesic farthest-point Voronoi diagram forSinP. It is known that the problem has antime lower bound. Previously, a randomized algorithm was proposed [Barba, SoCG 2019] that solves the problem inexpected time. The previous best deterministic algorithms solve the problem intime [Oh, Barba, and Ahn, SoCG 2016] or intime [Oh and Ahn, SoCG 2017]. In this paper, we present a deterministic algorithm that takestime, which is optimal. This answers affirmatively an open question posed by Mitchell in the Handbook of Computational Geometry two decades ago.
