In computer science and operations research, a genetic algorithm (GA) is a metaheuristic inspired by the process of natural selection that belongs to the larger class of evolutionary algorithms (EA). Genetic algorithms are commonly used to generate high-quality solutions to optimization and search problems by relying on biologically inspired operators such as mutation, crossover and selection.In addition, high-lift devices must work in harmony with other advanced concepts such as supersonic laminar flow control that are beneficial to supersonic cruise efficiency.

These requirements result in ample opportunity for innovative and aggressive aerodynamic development.This book contains a synthesis of the fundamental disciplines and applications involved in the description and analysis of aircraft flight.
