Abstract

We address the following problem: Given a simple polygon PP with nn vertices and two points ss and tt inside it, find a minimum link path between them such that a given target point qq is visible from at least one point on the path. The method is based on partitioning a portion of PP into a number of faces of equal link distance from a source point. This partitioning is essentially a shortest path map (SPM). In this paper, we present an optimal algorithm with O(n)O(n) time bound, which is the same as the time complexity of the standard minimum link paths problem.
