something strange with test cases 22, 23, and 25, the solution provided does not look like the shortest path (e.g. test case 22; the path 23-7-24-4-14 is shorter than the solution path 23-7-14), perhaps your solver is assuming triangular property of distances while the data provided does not have this property?
i'll look into it
I agree with you. i'm ammending my test cases now.
