Binary linear programming
WebOct 15, 2015 · How can I use linear constraints to describe the following condition: If x = z then y = 1 else y = 0. I tried to solve this problem by defining another binary variable i and a large-enough positive constant U and adding constraints y - U * i = 0; x - U * (1 - i) = z; Is this correct? linear-programming Share Improve this question Follow http://web.mit.edu/16.410/www/lectures_fall04/L18-19-IP-BB.pdf

WebAn integer programming problem is a mathematical optimization or feasibility program in which some or all of the variables are restricted to be integers. In many settings the term … WebLinear Programming is a generalization of Linear Algebra. It is capable of handling a variety of problems, ranging from finding schedules for airlines or movies in a theater to distributing oil from refineries to markets. The reason for this great versatility is the ease at which constraints can be incorporated into the model.

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. Certain special cases of linear programming, such as network flow problems and See more Linear programming problems can be converted into an augmented form in order to apply the common form of the simplex algorithm.
