    Abstract

    Motivated by a problem in music theory of measuring the distance between chords and scales we consider algo- rithms for obtaining a minimum-weight many-to-many matching between two sets of points on the real line. Given sets A and B, we want to find the best rigid translation of B and a many-to-many matching that minimizes the sum of the squares of the distances be- tween matched points. We provide a discrete algorithm that solves this continuous optimization problem, and discuss other related matters.
