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 three (writing) is often paired with quick timing, ensuring that viewers have less time to catch on to the pattern before the punch line hits. As a whole, the comedic rule of threes relies on setting up a pattern of two items and then subverting viewer expectations by breaking that pattern with the third item. One particularly notable example comes from The Dick Van Dyke Show - "Can I get you anything? Cup of coffee? Doughnut? Toupee?". Just like most comedic writing, the rule of threes in comedy relies on building tension to a comedic release. In the case of the rule
