Subtotal ordering -- a pedagogically advantageous algorithm for computing total degree reverse lexicographic order
David R. Stoutemyer
Total degree reverse lexicographic order is currently generally regarded as most often fastest for computing Groebner bases. This article describes an alternate less mysterious alg…
