The simulated annealing technique was one of the first stochastic minimization methods applied to electromagnetic imaging. It is an iterative method that, at each iteration, updates the current trial solution by exploiting probabilistic concepts. Population-based algorithms can be used for imaging purposes with different implementation schemes. It should also be noted that population-based algorithms seem to be particularly suitable for the inclusion of a priori information into the model. From an engineering standpoint, a priori information is very important, since it can be used for accelerating the reconstruction procedure. In this chapter, simulated annealing is discussed first. Then, some population-based methods, which have already been proposed for microwave imaging applications are considered. Specifically, there are the genetic algorithm, the differential evolution method, the particle swarm optimization method, and the ant colony optimization method.
