Figure Legend:
Bio-inspired route networks of the first three hubs for the 15-city problem. (a) The main hub is Toronto. Kelowna and Victoria are connected to Toronto through Edmonton, Saskatoon and Regina through Thunder Bay, and St. John’s through Halifax. (b) The main hub is Vancouver. Kelowna is connected to Vancouver through Saskatoon, Thunder Bay and Quebec City through Montreal, and Halifax and St. John’s through Toronto. (c) The main hub is Calgary. Thunder Bay and Quebec City are connected to Calgary through Montreal, and Halifax and St. John’s through Toronto.
