# 2. Genetic Algorithms: An Overview:
Genetic algorithms are a class of search algorithms that mimic the process of natural selection and evolution. They are based on the principles of genetics, including reproduction, crossover, and mutation, to generate a population of potential solutions. These solutions then undergo selection, crossover, and mutation operations to evolve and improve iteratively. The iterative process continues until an optimal solution is found or a predefined termination criterion is met.
