Generalized Watchman Route Problem with Discrete View Cost
In this paper, we introduce a generalized version of the Watchman Route Problem (WRP) where the objective is to plan a continuous closed route in a polygon (possibly with holes) a...

Approximate shortest path algorithms for sequences of pairwise disjoint simple polygons
Assume that two points p and q are given and a finite ordered set of simple polygons, all in the same plane; the basic version of a touring-a-sequence-of-polygons problem (TPP) is...

The Class of Simple Cube-Curves Whose MLPs Cannot Have Vertices at Grid Points
We consider simple cube-curves in the orthogonal 3D grid of cells. The union of all cells contained in such a curve (also called the tube of this curve) is a polyhedrally bounded s...

Space-Query-Time Tradeoff for Computing the Visibility Polygon
Abstract. Computing the visibility polygon, VP, of a point in a polygonal scene, is a classical problem that has been studied extensively. In this paper, we consider the problem of...

Computing simple paths among obstacles
Given a set X of points in the plane, two distinguished points s,t X, and a set of obstacles represented by line segments, we wish to compute a simple polygonal path from s to t...
