# This module represents a parameters object for genetic algorithm.
#
# Parameters include:
# (1) genotype_length       (number of bits used for encoding)
# (2) population_size       (number of chromosomes in a single generation)
# (3) maximum_generations   (number of generations after which execution stops)
# (4) mutation_rate         (probability of a mutation occurring)
# (5) crossover_rate        (probability of a crossover occurring)
