error in /deploy/precalculation

[rahelehzarei]

Hi

When I run the ./deploy/precalculation with the map from my own city, it gives me the following error:
terminate called after throwing an instance of 'std::out_of_range'
what(): basic_string::substr: __pos (which is 18446744073709551615) > this->size() (which is 26)
Aborted (core dumped)

Do you know what's the cause of this error and how can I fix it?

Thanks

You need to specify a valid multi-level partitioning to the program. This project does not include a program to compute such a partitioning. You could implement it yourself (e.g. inertial flow [0]) or search for an open-source graph / road network partitioning algorithm.

Thank you Micheal.
I could make it work by using buffoon as multi level partitioning program.
I just was wondering how did you use buffoon? I mean what was the value for parameter k when you run buffoon? I would like to make an mlp file same as the one you have in example folder.

Can KaHIP be used？
