Linear indicates that no variables are raised to higher powers, such as squares. For this class, the problems involve minimizing (or maximizing) a linear objective function whose variables are real numbers that are constrained to satisfy a system of linear equalities and ...Linear programming (LP) is an optimization technique that is used to find the best solution, from a specified objective function, subject to some constraints. It is applied in sundry industries ranging from finance to e-commerce, so it’s well worth knowing if you are a Data Scientist.Even if an optimization problem is feasible, it may have no optimum solution and, therefore, becomes an unbounded problem. 1.3 Types of Linear Programming Linear programming can be integer linear programming (ILP), binary integer programming (BIP), and mixed integer linear programming (MILP). The decision variables of ILP are positive
