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 Wynn and Rule Rule Wynn and Rule Rule Wynn and Rule was an Albertan architectural firm that had offices in Calgary and Edmonton. The firm is noted for its prominent role in bringing modern architecture to Alberta. Founded by John Ulric Rule (1904-1978) and Gordon K. Wynn (1910-1994) in Edmonton in 1938, they were joined a year later by Rule's brother, Peter Leitch Rule (1913-1964). The initial partnership came about as neither Rule nor Wynn could find work. All three partners were graduates of the school of architecture at the University of Alberta. During World War II the Rule brothers's father, also named
