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
Flemming Rule from its welfare program in what became known as the "Louisiana Incident." This was done because the children had been born outside of wedlock, and were considered illegitimate by the state. Similar types of welfare denial had occurred in other states. In response to this, the Louisiana Department of Health, Education and Welfare, administrator of the income assistance program, implemented the Fleming Rule. A 1997 article by Claudia Lawrence-Webb claimed that the child welfare system had problems fairly representing children of color and signified this problem was due to the Fleming Rule. Webb suggested that the rule was implemented poorly,
