Webbsimplex method, the equation Ax+y= bmust have a solution in which n+1 or more of the variables take the value 0. Generically, a system of mlinear equations in m+ nunknown does not have solutions with strictly more than nof the variables equal to 0. If we modify the linear system Ax+y= bby perturbing it slightly, we should expect that such a ...

Webbanalyzed in theory are the so-called parametric simplex methods, due to the useful geometric characterization of the paths they follow. The rst such method, and the main one used in the context of smoothed analysis, is the parametric objective method of Gass and Saaty [GS55], dubbed the shadow (vertex) simplex method by Borgwardt [Bor77].
