Let P be a set of 2n points in the plane, and let MC (resp., MNC) denote a bottleneck matching (resp., a bottleneck non-crossing matching) of P. We study the problem of computing MNC. We present an O(n1.5log0.5n)-time algorithm that computes a non-crossing matching M of P, such that $bn(M) \le 2\sqrt{10} \cdot bn(M_{\rm NC})$, where bn(M) is the length of a longest edge in M. An interesting implication of our construction is that $bn(M_{\rm NC})/bn(M_{\rm C}) \le 2\sqrt{10}$. We also show that when the points of P are in convex position, one can compute MNC in O(n3) time. (In the full version of this paper, we also prove that the problem is NP-hard and does not admit a PTAS.) |
