The Cox–Zucker machine is an algorithm created by David A. Cox and Steven Zucker. This algorithm determines if a given set of sections provides a basis (up to torsion) for the Mordell–Weil group of an elliptic surface ES where S is isomorphic to the projective line.[1]

The algorithm was first published in the 1979 paper "Intersection numbers of sections of elliptic surfaces" by Cox and Zucker[2] and it was later named the "Cox–Zucker machine" by Charles Schwartz in 1984.[1]
