Genetic Algorithms (GAs), proposed in 1962 by Professor Holland at the University of Michigan, are a parallel stochastic search optimization method that simulates natural genetic mechanisms and biological evolution. This approach introduces the biological evolution principle of "survival of the fittest" into encoded parameter populations, where individuals are selected based on fitness functions through genetic operations including selection, crossover, and mutation. High-fitness individuals are preserved while low-fitness individuals are eliminated, creating new populations that inherit previous generation information while demonstrating superior performance. The algorithm iterates until convergence criteria are met, typically involving population initialization, fitness evaluation, and genetic operator application in computational implementations.
