Increasing-Chord Graphs On Point Sets Vol. 19, no. 2, pp. 761-778, 2015. Regular paper. Abstract We tackle the problem of constructing increasing-chord graphs spanning point sets. We prove that, for every point set P with n points, there exists an increasing-chord planar graph with O(n) Steiner points spanning P. The main intuition behind this result is that Gabriel triangulations are increasing-chord graphs, a fact which might be of independent interest. Further, we prove that, for every convex point set P with n points, there exists an increasing-chord graph with O(n logn) edges (and with no Steiner points) spanning P. Submitted: October 2014.
