Center node: "minimum link paths revisited"
  Abstract: A path or a polygonal domain is C-oriented if the orientations of its edges belong to a set of C given orientations; this is a generalization of the notable rectilinear case (C = 2). We study exact and approximation algorithms for minimum-link C-oriented paths and paths with unrestricted orientations, both in C-oriented and in general domains. Our two main algorithms are as follows: #R##N#A subquadratic-time algorithm with a non-trivial approximation guarantee for general (unrestricted-orientation) minimum-link paths in general domains. #R##N#An algorithm to find a minimum-link C-oriented path in a C-oriented domain. Our algorithm is simpler and more time-space efficient than the prior algorithm. #R##N#We also obtain several related results: #R##N#- 3SUM-hardness of determining the link distance with unrestricted orientations (even in a rectilinear domain). #R##N#- An optimal algorithm for finding a minimum-link rectilinear path in a rectilinear domain. The algorithm and its analysis are simpler than the existing ones. #R##N#- An extension of our methods to find a C-oriented minimum-link path in a general (not necessarily C-oriented) domain. #R##N#- A more efficient algorithm to compute a 2-approximate C-oriented minimum-link path. #R##N#- A notion of "robust" paths. We show how minimum-link C-oriented paths approximate the robust paths with unrestricted orientations to within an additive error of 1.
