devoted to describing how systems behave, e.g. in the laws of physics. The advent of computers, however, has brought an emphasis on using mathematics to make systems behave in chosen ways, and choices lead to questions of optimization. Equations −→ inequalities: Optimization typically deals with variables that have to lie
