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 mathematical optimization. More formally, linear programming is a technique for the optimization of a linear objective function , subject to linear equality and linear inequality constraints. Its feasible region is a convex polytope , which is a set defined as the intersection of finitely many half spaces , each of which is defined by a linear inequality. Its objective function is a real -valued affine linear function defined on this polyhedron. A linear programming algorithm finds a point in the polytope where this function has the smallest or largest value if such a point exists.
The non-graphical method is much more complicated, and is perhaps much harder to visualize all the possible solutions for a system of inequalities. However, when you have several equations or several variables, graphing may be the only feasible method. Linear programming involves finding an optimal solution for a linear equation, given a number of constraints. A common application of systems of inequalities is linear programming. Linear programming is a mathematical method for determining a way to achieve the best outcome for a list of requirements represented as linear relationships.

Linear Programming: Introduction page 1 of 5. Sections: Optimizing linear systems, Setting up word problems. Linear programming is the process of taking various linear inequalities relating to some situation, and finding the "best" value obtainable under those conditions. A typical example would be taking the limitations of materials and labor, and then determining the "best" production levels for maximal profits under those conditions. In "real life", linear programming is part of a very important area of mathematics called "optimization techniques".

Linear programming , mathematical modeling technique in which a linear function is maximized or minimized when subjected to various constraints. This technique has been useful for guiding quantitative decisions in business planning, in industrial engineering , and—to a lesser extent—in the social and physical sciences. The solution of a linear programming problem reduces to finding the optimum value largest or smallest, depending on the problem of the linear expression called the objective function.
In mathematics a linear inequality is an inequality which involves a linear function. A linear inequality contains one of the symbols of inequality:. A linear inequality looks exactly like a linear equation , with the inequality sign replacing the equality sign. The solution set of such an inequality can be graphically represented by a half-plane all the points on one "side" of a fixed line in the Euclidean plane. Then, pick a convenient point not on the line, such as 0,0.
Передо мной лежит отчет, из которого следует, что ТРАНСТЕКСТ бьется над каким-то файлом уже восемнадцать часов и до сих пор не вскрыл шифр. Джабба обильно полил приправой кусок пирога на тарелке. - Что-что. - Как это тебе нравится. Он аккуратно размазал приправу кончиком салфетки. - Что за отчет.
Надо звонить Стратмору. - Домой? - ужаснулся Бринкерхофф. - Вечером в субботу. - Нет, - сказала Мидж. - Насколько я знаю Стратмора, это его дела.
22: РУЧНОЕ ОТКЛЮЧЕНИЕ ГЛАВА 35 Беккер в шоке смотрел на Росио. - Вы продали кольцо. Девушка кивнула, и рыжие шелковистые волосы скользнули по ее плечам. Беккер молил Бога, чтобы это оказалось неправдой.
Подними! - срывающимся голосом завопил панк.
