Abstract
Optimization is a part of nature and, inevitably, an integral part of human life. Any decision we make is an attempt to process an optimal or almost optimal situation. From a general point of view, any optimization problem can be considered as a decision-making problem, and the question is whether or not there is any better solution to the problem than the one we have found. In other words, optimization means to reach a solution as good as possible to lead us to a better performance of the system under consideration. According to the description of Beightler et al. [1], optimization is a three-step decision-making process: (1) modeling the problem based on the knowledge of the problem, (2) finding measures of effectiveness or the objective function, and (3) the optimization method or optimization theory. It is valid to say that the entire field of optimization, especially the latter step, merely benefited by the development and improvement of computers which started in the mid-1940s.
