<h3>Genetic Algorithm (GA) Optimizer</h3>
<p>Genetic algorithm optimizers are robust, stochastic search methods, modeled on the principles and concepts of natural selection and evolution. As an optimizer, the powerful heuristic of the GA is effective at solving complex, combinational, and related problems. GA optimizers are particularly effective when the goal is to find an approximate global maximum in a high-dimension, multi-modal function domain, in a near-optimal manner. This is particularly true when the problem can be cast in a combinational form, a form in which GAs excel.</p>
