This first line is just python imports to use different commands. Travelling salesman problem (tsp) : The hamiltonian cycle problem is to find if there exists a tour that visits every city exactly once. We can reproduce this with: Search_parameters = pywrapcp.defaultroutingsearchparameters() search_parameters.first_solution_strategy = ( routing_enums_pb2.firstsolutionstrategy.path_cheapest_arc) # solve the problem.
