示例1: main

# 需要导入模块: from algorithm import Algorithm [as 别名]
# 或者: from algorithm.Algorithm import fitness_function [as 别名]
def main():
    parser = argparse.ArgumentParser(description='Highway builder.')
    parser.add_argument('-a', required=True, type=float, help='Roads length factor.')
    parser.add_argument('-b', required=True, type=float, help='Path length factor.')
    parser.add_argument('-i', default=20, type=int, help='Number of iterations.')

    args = parser.parse_args()

    if args.a < 0:
        print('Roads length factor should be greater or equal 0.')
        exit()

    if args.b < 0:
        print('Path length factor should be greater or equal 0.')
        exit()

    if args.i < 1:
        print('Number of iterations should be greater than 0.')

    point_tuples = read_cities()
    alg = Algorithm(point_tuples, roads_length_factor=args.a, paths_length_factor=args.b, iterations=args.i)

    iters_ended = alg.simulated_annealing()

    fitness = alg.fitness_function(alg.state)
    file_name = "result"
    millis = int(round(time.time() * 1000))
    file_name += str(millis)
