Example text

Given a planar straight-line graph G(V, E), the horizontal visibility map of G can be computed in O(n log n) time, where n = |V|. However, if G is a simple polygon then the horizontal visibility map can be computed in linear time. 11 Updates of sweep-line status. (a) vi is regular (b) vi is a V-cusp and (c) vi is a Λ-cusp. 2 Triangulation In this section we consider triangulating a planar straight-line graph by introducing noncrossing edges so that each face in the final graph is a triangle and the outermost boundary of the graph forms a convex polygon.

Or equivalently if M(i, k) < M(i, l) implies M(j, k) < M(j, l) for any i < j and k < l, then M is totally monotone. The algorithm for solving the row maxima-searching problem is due to Aggarwal et al. [2], and is commonly referred to as the SMAWK algorithm. Specifically the following results were obtained: O(m log n) time for an n × m monotone matrix, and θ(m) time, m ≥ n, and θ(m(1 + log(n/m))) time, m < n, if the matrix is totally monotone. We use as an example the distance matrix between pairs of vertices of a convex n-gon P, represented as a sequence of vertices p1 , p2 , .

We will show below that the all farthest neighbor problem for each vertex of a convex n-gon can be solved in O(n) time. A straightforward divide-and-conquer algorithm for the row maxima-searching problem in monotone matrices is as follows. ALGORITHM MAXIMUM_D&C 1. Find the maximum entry j = j(i), in the ith row, where i = n2 . 2. Recursively solve the row maxima-searching problem for the submatrices M[1, . . , i − 1; 1, . . , j] when i, j > 1 and M[i + 1, . . , n; j, . . , m] when i < n and j < m.
