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
Plain meaning rule clear meaning that makes sense within that context. If Parliament does not like the literal interpretation, then it must amend the legislation. The "plain meaning rule" has sometimes been applied to the interpretation of contracts, particularly in conjunction with the parol evidence rule. Such a use is controversial. Plain meaning rule The plain meaning rule, also known as the literal rule, is one of three rules of statutory construction traditionally applied by English courts. The other two are the "mischief rule" and the "golden rule". The plain meaning rule dictates that statutes are to be interpreted using the ordinary meaning
