Different scenarios on dominant points and point sets. a A scenario where the fourth dominant point is non-insertible, and the point set is non-reducible with respect to v i ,i=1,…,3; b A scenario where the fourth dominant point is non-insertible, and the point set is reducible with respect to v i ,i=1,…,3; c A scenario where the fourth dominant point is insertible with respect to v i ,i=1,…,3, and the algorithm will continue to locate the fifth dominant point
