Linear programming maximizes the minimum distance problem

WebThe goal of linear programming is to find the best solution to a problem. This is done by maximizing or minimizing the objective function. The objective function is a function that defines some quantity that should be minimized or maximized. The arguments of the objective function are the same variables that are used in the constraints.
