Hi,

I figure it out! That may happen when there are only links from 0 to 3 and from 
134 to 3!


==================================

Hi,


I'm trying the function get_all_shortest_paths in python, and I've gotten some 
strange result as following:


>>> g.get_all_shortest_paths(0,134,mode='OUT')
[[0, 33, 134]]
>>> g.get_all_shortest_paths(0,134,mode='IN')
[[0, 33, 134], [0, 11, 134]]
>>> g.get_all_shortest_paths(0,134,mode='ALL')
[[0, 33, 134], [0, 33, 134], [0, 33, 134], [0, 33, 134], [0, 11, 134], [0, 11, 
134], [0, 3, 134]]



I can figure out that there are both links from 0 to 33 and from 33 to 0. Maybe 
also links from 33 to 134 and 134 to 33.


but where does the path [0, 3, 134] come from? why does not it exist in neither 
of the results of IN mode and OUT mode?


Thanks
