What algorithm can I use to describe a specified gradient (N/M) approximately as the sum of a set of rational fractions { (n1/m1) + (n2/m2) … } ? Design constraints: The algorithm takes as input (N, M), describing the true gradient N/M. N and M are integers. M is typically around 100–1000. N ranges widely,Read more
