WebJan 23, 2024 · The cost of travel is the cost to travel the distance between two nodes. In the case of the solver, you need to set an arc cost evaluator function that does this calculation. This function takes as parameter the transit_callback_index returned by the distance_callback. In our case, the travel cost is simply the distance between the locations. bracelets with saints on themWebSep 30, 2024 · vrp_plot.py.
