WebbLet us further emphasize the implications of solving these problems by the simplex method. The opti-mality conditions of the simplex method require that the reduced costs of basic variables be zero. Hence, if xˆ1 > 0, then c1 =6 −1 2 yˆ1 − ˆy2 =0; if xˆ3 > 0, then c3 =13 − ˆy1 −4yˆ2 =0. WebbThe answer is easy. They both (simplex and interior point methods) are a mature field from an algorithmic point of view. They both work very well in practice. The good reputation of I.P.M. (interior point methods) is due to its polynomial complexity in the worst case. That is not the case for simplex which has combinatorial complexity.
Webbsimplex method was given by Spielman and Teng (JACM ‘04), who developed the notion of smoothed analysis. Starting from an arbitrary linear program (LP) with dvariables and nconstraints, Spielman ... procedure was in fact generalized by Lemke [Lem65] to solve linear complementarity problems.

Webb23 juni 2024 · The Big M Method Procedure If an LP has any > or = constraints, the Big M method or the two-phase simplex method may be used to solve the problem. The Big M method is a version of the Simplex Algorithm that first finds a best feasible solution by adding “artificial” variables to the problem. http://web.mit.edu/15.053/www/AMP-Chapter-04.pdf
