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
Rule of Saint Francis Rule of Saint Francis As known, Saint Francis founded three orders and gave each of them a special rule. Here, only the rule of the first order is to be considered, i.e., that of the Order of Friars Minor. There are, as in so many other points in the life of St. Francis, not a small amount of doubt and controversy about the Rule of St. Francis. Whether St. Francis wrote several rules or one rule only, with several versions, whether he received it directly from heaven through revelations, or whether it was the fruit of his long experiences, whether
