    Abstract

    Given a set P of n points in the plane in general position, and a set of non-crossing segments with endpoints in P, we seek to place a new point q such that the constrained Delaunay triangulation of P ∪ {q} has the largest possible minimum angle. The expected running time of our (randomized) algorithm is O(n2 log n) on any input, improving the near-cubic time of the best previously known algorithm. Our algorithm is somewhat complex, and along the way we develop a simpler cubic-time algorithm quite different from the ones already known.
