Analogy

Variants of the Simplex Methodpts were made to combine them. At first, two important variants will be presented in the following two sections respectively, both of which prefixed by “primal-dual” because they execute primal as well as dual simplex steps, though they are based on different ideas. More recent variants of such type will be presented later in Chap. 18.

byline

Interior-Point Methodached, or unboundedness of the problem is detected. Nevertheless, it would go through an exponential number of vertices of the polyhedron (Sect. 3.8), and even stall at a vertex forever because of cycling along degenerate edges (Sect. 3.6).

MOTTO

Simplex Phase-I Methodbasis or its inverse. The task of a Phase-I method is to provide such a starting point to Phase-II for achieving optimality. Such a two-Phase methodology has been successful in practice, compared with one-Phase, like the big-M.

Introduction,As intelligent creatures, human beings plan and carry out activities with pre-set objectives. Early human ancestors relied on their experience, whereas their modern-day descendants use scientific methods to aid their decision making in order to be more efficient and effective.

Agility

Simplex MethodThe simplex method is an efficient and widely used LP problem solver. Since proposed by George B. Dantzig in 1947, it has been dominating this area for more than 60 years.

Dual Simplex Phase-l MethodThe mission of a dual Phase-I procedure is to provide an initial dual feasible simplex tableau (or basis) to the dual simplex method.
