Cunningham's Rule constructions because they tend to average out how many times a variable pivots. It has recently been shown by David Avis and Oliver Friedmann that there is a family of linear programs on which the simplex algorithm equipped with Cunningham's rule requires exponential time. Cunningham's Rule In mathematical optimization, Cunningham's rule (also known as least recently considered rule or round-robin rule) is an algorithmic refinement of the simplex method for linear optimization. The rule was proposed 1979 by W.H. Cunningham to defeat the deformed hypercube constructions by Klee and Minty et. al. (see, e.g. Klee–Minty cube). Cunningham's rule assigns a
Offshore Racing Congress Rule produce the extreme and often unsafe designs which became the hallmark of the IOR rule. To encourage the growth of the rule, two versions have been developed. The ORC-International rule (ORCi) is the full complexity, highly developed version for top level championship racing. An ORC-Club rule has also been developed, which is a simplified version more easily used by smaller clubs who have less resources. Offshore Racing Congress Rule The Offshore Racing Congress Rule is a system of handicapping sailboats for the purpose of racing. It is managed by the Offshore Racing Congress (ORC) and is usually referred to in
