Your program will be called find_route, and will take exactly commandline arguments as follows: find_route input_filename origin_city destination_city heuristic_filename An example command line is: find_route input1.txt Bremen Kassel (For doing Uninformed search) or find_route input1.txt Bremen Kassel h_kassel. txt (For doing Informed search)
