Genetic Algorithms, first introduced by John Holland in the 1960s, are a subset of evolutionary algorithms inspired by biological evolution. These algorithms simulate the process of natural selection to find approximate solutions to optimization and search problems. The fundamental components of GAs include:

  1. Chromosomes: These are candidate solutions to the problem encoded as strings of genes.
  2. Genes: The basic building blocks of chromosomes, representing specific features or parameters.
  3. Population: A collection of chromosomes that evolves over generations.
  4. Fitness Function: A measure of how well a chromosome solves the problem at hand.
  5. Selection: The process of choosing parents based on their fitness to produce offspring.
  6. Crossover: The recombination of genetic material from parents to create new offspring.
  7. Mutation: A small, random change applied to an offspring’s chromosome.
  8. Termination Criteria: Conditions for ending the algorithm, such as a maximum number of generations or achieving a certain fitness level.
