Linear programming (LP), also called linear optimization, is a method to achieve the best outcome (such as maximum profit or lowest cost) in a mathematical model whose requirements are represented by linear relationships. Linear programming is a special case of mathematical programming (also known as … Meer weergeven The problem of solving a system of linear inequalities dates back at least as far as Fourier, who in 1827 published a method for solving them, and after whom the method of Fourier–Motzkin elimination is named. Meer weergeven Standard form is the usual and most intuitive form of describing a linear programming problem. It consists of the following three parts: • A … Meer weergeven Every linear programming problem, referred to as a primal problem, can be converted into a dual problem, which provides an upper bound to the optimal value of the … Meer weergeven It is possible to obtain an optimal solution to the dual when only an optimal solution to the primal is known using the complementary slackness theorem. The theorem states: Meer weergeven Linear programming is a widely used field of optimization for several reasons. Many practical problems in operations research can be expressed as linear programming problems. Certain special cases of linear programming, such as network flow problems and Meer weergeven Linear programming problems can be converted into an augmented form in order to apply the common form of the simplex algorithm. This form introduces non-negative slack variables to replace inequalities with equalities in the constraints. … Meer weergeven Covering/packing dualities A covering LP is a linear program of the form: Minimize: b y, subject to: A y ≥ c, y ≥ 0, such that the matrix A and the vectors b and c are non-negative.
