    Study Notes

    • A genetic algorithm (GA) is a computer program that tries to find a good solution to a problem by evolving a population of candidate solutions.
    • The GA maintains a population of solutions and makes it evolve by iteratively applying a set of stochastic operators.
    • The GA has been subject of many (early) studies and still often used as a benchmark for novel GAs.
    • The GA shows many shortcomings, e.g. it is too restrictive in its representation of solutions, mutation and crossovers only applicable for bit-string and integer representations, and selection mechanism sensitive for converging populations with close fitness values.
    • We will use Tournament Selection to choose a solution and place it in the mating pool. Two other solutions will be picked and another solution in the mating pool will be filled up with the better solution.
    • Order-1 crossover is explorative and mutation is exploitative.
    • Mating individualsto generate pop_size offspring is a steady-state replacement process.
    • Each individualsurvives for exactly one generation and the entire set of parents is replaced by the offspring.
    • The elitism option is used to keep one or more of the best solutions discovered so far and copy them to the next generation.
    • Schema theory seeks to give a theoretical justification for the efficacy of the field of genetic algorithms.
    • What is a schema:
    • a template for new gene arrangements  {0,1,*} where * is a don't care.
    • Schema is favorable traits in a solution, where a favorable schema is called an above average schema.
