Before revision:  Two skeletal algorithms are defined and instantiated with different separation oracles to yield a sequential convex hull algorithm, a new version of Benson's algorithm with the theoretically best possible iteration count, and the new algorithm.
After revision:  Two skeletal algorithms are defined and instantiated with different separation oracles to yield a sequential convex hull algorithm, a new version of Benson's algorithm with the theoretically best possible iteration count, the dual algorithm of Ehrgott, L\"ohne and Shao, and the new algorithm.
