Emerging Evolutionary Algorithms for Antennas and Wireless Communications — Recommend this title to your library

Thank you

Your recommendation has been sent to your librarian.

This chapter briefly introduces basic optimization concepts. Optimization problems exist in our everyday life. We often wonder about the route with less traffic to work, the less money to spend in various activities, or the best work schedule. Optimization can be thought as the art of making good decisions. In more precise manner, we may define optimization as the process of changing a system's state (or values of some unknown variables) toward a state of a minimum or maximum property. Several optimization problems exist in the whole engineering domain. A common problem in antennas design is to find the best geometry for a given antenna, while in wireless communications the association between a base station and user in an optimal manner is a very popular optimization problem.
