### Description

The naming convention for the structures used during a computation is as follows.

STRUCTURE MEANING -------------------------------------------------------------------------- U Order ideal; so called computing universe; named "L" in [1]. V Set of polynomials with pairwise different leading terms; represents a linear basis. W' Set of polynomials with pairwise different leading terms; represents a linear basis extension of V. O Order ideal consisting of elements U \ { LT(v) : v in V }.
