create_initial_solutions() → List[S]

Creates the initial list of solutions of a metaheuristic.

evaluate(solution_list: List[S])

Evaluates a solution list.

get_name() → str

get_result() → R

replacement(population: List[S], offspring_population: List[S]) → List[S]

Replace least-fit population with new individuals.

reproduction(population: List[S]) → List[S]

Breed new individuals through crossover and mutation operations to give birth to offspring.

selection(population: List[S]) → List[S]

Select the best-fit individuals for reproduction (parents).

stopping_condition_is_met() → bool

The stopping condition is met or not.
