WebbThe Simplex method is an approach for determining the optimal value of a linear program by hand. The method produces an optimal solution to satisfy the given constraints and produce a maximum zeta value. To use the Simplex method, a given linear programming model needs to be in standard form, where slack variables can then be introduced.

WebbAn unbounded solution of a linear programming problem is a solution whose objective function is infinite. A linear programming problem is said to have unbounded solution if its solution can be made infinitely large without violating any of the constraints in the problem. Since there is no real applied problem which has infinite returns, hence ...

WebbIn this week, we first introduce the standard form and the basic solutions of a linear program. With the above ideas, we focus on the simplex method and study how it efficiently solves a linear program. Finally, we discuss some properties of unbounded and infeasible problems, which can help us identify whether a problem has optimal solution.

WebbFundamental theorem of LP Theorem – For a feasible linear program in its standard form, the optimum value of the objective over its nonempty feasible region is (a) either unbounded or (b) is achievable at least at one extreme point of the feasible region. Four possible states of LP – 1-Feasible with a unique optimum solution -(b) – 2-Feasible with … WebbSimplex method theory. Simplex method is an iterative procedure that allows to improve the solution at each step. This procedure is finished when isn't possible to improve the solution. Starting from a random vertex value of the objective function, Simplex method tries to find repeatedly another vertex value that improves the one you have before.
