linear programming 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 and objective are represented by linear function#As a polynomia ...

integer programming An 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 refers to integer linear programming (ILP), in which the objective ...

nonlinear programming In mathematics, nonlinear programming (NLP) is the process of solving an optimization problem where some of the constraints are not linear equalities or the objective function is not a linear function. An optimization problem is one of calculation ...

stochastic programming In the field of mathematical optimization, stochastic programming is a framework for modeling optimization problems that involve uncertainty. A stochastic program is an optimization problem in which some or all problem parameters are uncertain, ...

applications. It is designed to solve optimization problems that arise in areas of business, industry, research, and government. The LINDO package includes sample applications related to product distribution, ingredient blending, production, personnel scheduling, inventory management. LINDO also creates "What's''Best!''" which is an add-in for linear, integer and nonlinear optimization. First released for

. * The LINDO package contains Stochastic, Linear, Nonlinear (convex & nonconvex/Global), Quadratic, Quadratically Constrained, Second Order Cone and Integer solvers. * It provides tools for analysis of infeasible linear, integer and nonlinear models. * LINDO supports Multiple Objective Optimization. For linear models, users can provide a prioritized list of objective functions, and LINDO will perform Lexico/Pre-emptive priority optimization. * The Multi-Start NLP Solver in LINDO makes it possible for users to specify a target value for the objective function. As soon as any multi-start thread achieves a specified target all threads stop. * With the release of LINDO API 7.0, LINDO
