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
Mischief rule Mischief rule The mischief rule is one of three rules of statutory interpretation traditionally applied by English courts. The other two are the "plain meaning rule" (also known as the "literal rule") and the "golden rule". The main aim of the rule is to determine the "mischief and defect" that the statute in question has set out to remedy, and what ruling would effectively implement this remedy. In applying the mischief rule, the court is essentially asking what part of the law did the law not cover, but was meant to be rectified by Parliament in passing the bill. The
