So far, these types of problems have typically been modelled and solved by means of linear programming. However, many real-life phenomena are of a nonlinear nature, which is why we need tools for nonlinear programming capable of handling several conflicting or incommensurable objectives. The intention has been to provide a consistent summary that may help in selecting an appropriate method for the problem to be solved.
Problems related to real-life applications often contain irregularities and nonsmoothnesses.
