WebLinear 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 ). WebInteger programming expresses the optimization of a linear function subject to a set of linear constraints over integer variables. The statements presented in Linear programming: a production planning exampleare all linear programming models. However, linear programs with very large numbers of variables
