Given a set of n points in the plane, any β-skeleton and [γ0, γ1] graph can be computed in quadratic time. The presented algorithms are optimal for β values that are less than 1 and [γ0, γ1] values that result in non-planar graphs. For β = 1, we show a numerically robust algorithm that computes Gabriel graphs in quadratic time and degree 2. We finally show how a β-spectrum can be computed in optimal O(n2) time.
