To run the problem from
solomon set, simply specify solomon as a type. The following command solves solomon problem
defined in RC1_10_1.txt and stores solution in RC1_10_1_solution.txt:
vrp-cli solve solomon RC1_10_1.txt -o RC1_10_1_solution.txt
Optionally, you can specify initial solution to start with:
vrp-cli solve solomon RC1_10_1.txt --init-solution RC1_10_1_solution_initial.txt -o RC1_10_1_solution_improved.txt
