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
President's rule obtaining the consent of the President of India. If it is not possible to revoke Governor's rule within six months of imposition, the President's Rule under Article 356 of the Indian Constitution is imposed. There is little practical difference between the two provisions. Following its landmark judgment in the 1994 "Bommai" case, the Supreme Court of India has restricted arbitrary impositions of President's rule. Chhattisgarh and Telangana are the only states where President's rule has yet to be imposed. In practice, president's rule has been imposed under different circumstances: If approved by both houses, President's Rule can continue for 6
