Re: [igraph] Python : ImportError: No module named core

[Matthew Walker]

Hi,

I dont know if this is useful to you (as I'm certain your implementation 
would be more efficient), but attached are my two efforts for 
implementing a "radius" measure: one in python and one in C/C++.

For the C++ I used unit++ [1] to test my code (but to be honest it's the 
first time I've worked with that too, so it might not be the best 
example of it's usage!)

Cheers,

Matthew
