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 … See more 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. See more Standard form is the usual and most intuitive form of describing a linear programming problem. It consists of the following three parts: See more 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 primal … See more It is possible to obtain an optimal solution to the dual when only an optimal solution to the primal is known using the complementary … See more 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.
