on Darwin's theory of "survival of the fittest" and biological evolution of genetic mechanisms. Algorithms act on each generation of genes, and each gene is a possible solution to the problem. Generally, there are four steps to apply a genetic algorithm: 1. Randomly select an individual and perform crossover 2. Variation 3. Calculate fitness 4. Select the next generation of individuals The algorithm's stop condition is generally the completion of a specified number of iterations or
