摘要	In this paper, we investigate the maximum weight triangulation of a point set in the plane. We prove that the weight of maximum weight triangulation of any planar point set with diameter D is bounded above by ((2epsilon+2)(.)n + pi(1-2epsilon)/8epsilonroot1-epsilon(2) + pi/2 - 5(epsilon+1))D, where epsilon for 0 < epsilon less than or equal to 1/2 is a constant and n is the numb er of points in the set. If we use 'spoke-scan' algorithm to find a triangulation of the point set, we obtain an approximation ratio of 4.238. Furthermore, if the point set forms a 'semi-lune' or a 'semi-circled' convex polygon', then its maximum weight triangulation can be found in O(n(2)) time.
