Bottleneck bichromatic non-crossing matchings using orbits

Given a set of n red and n blue points in the plane, we want to match red points with blue points by straight line segments so that the segments do not cross. Bottleneck matching is such a matching that minimizes the length of the longest segment. We develop a range of tools for dealing with non-crossing matchings of points in convex position, which enable us to solve the problem of finding bottleneck matchings of points in convex position in O(n2) time. Combining the same set of tools with a geometric analysis, we design an O(n)-time algorithm for the case where the given points lie on a circle. Joint work with Marko Savić.
