Performing a sequence of degenerate iterations, all representing the same extreme point with the objective function value remaining unc hanged is called cycling.
WebWhile degeneracy is the rule in practice and stalling is common, cycling is rare in practice. A discussion of an example of practical cycling occurs in Padberg. Bland's rule prevents cycling and thus guarantees that the simplex algorithm always terminates. ... Simplex Method A tutorial for Simplex Method with examples ...
