Python read_coords Examples

Example #1

File: profile_tsp.py Project: lavarini/TPS-HILLCLIMB-PYTHON

import tsp
import profile

coords=tsp.read_coords(file('city500.txt'))
init_function=lambda: tsp.init_random_tour(len(coords))
matrix=tsp.cartesian_matrix(coords)
objective_function=lambda tour: -tsp.tour_length(matrix,tour)
move_operator=tsp.reversed_sections
max_iterations=1000

#profile.run('tsp.run_hillclimb(init_function,move_operator,objective_function,max_iterations)')
profile.run('tsp.run_evolve(init_function,move_operator,objective_function,max_iterations)')

Example #2

File: test_tsp.py Project: mabounassif/traveling_salesman

def test_read_coords():
    coord_file="""0.0,0.0\n0,1\n1,0.0\n1.0,1.0""".split()
    coords=tsp.read_coords(coord_file)
    
    assert 4 == len(coords)
    assert [(0.0,0.0),(0.0,1.0),(1.0,0.0),(1.0,1.0)] == coords

Example #3

File: test_tsp.py Project: ireneerl/BPTree

def test_read_coords():
    coord_file="""0.0,0.0\n0,1\n1,0.0\n1.0,1.0""".split()
    coords=tsp.read_coords(coord_file)

    assert 4 == len(coords)
    assert [(0.0,0.0),(0.0,1.0),(1.0,0.0),(1.0,1.0)] == coords
