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 by decree Rule by decree Rule by decree is a style of governance allowing quick, unchallenged creation of law by a single person or group, and is used primarily by dictators, absolute monarchs and military leaders. The expression is also sometimes used when describing actions of democratic governments that are perceived to unduly bypass parliamentarian or popular scrutiny. Rule by decree allows the ruler to arbitrarily create law, without approval by a legislative assembly. When states of emergency such as martial law are in place, rule by decree is common. While rule by decree is easily susceptible to the whims and corruption
