Hi Andrew,
2010/2/8 Andrew Sutton
The code below crashes (segfault) in the max_flow() function. Could you
tell me what am I doing wrong ?
It seems to work when I set a capacity capacity[p2.first] with a value
smaller than 10 (capacity[p.first]). Am I missing something? Do I correctly
use the reverse property_map?
Where precisely does it crash?
Here is the backtrace from gdb (sorry ...). Eric, no I did not forget to add
vertices in my graph. It is build in another function that I removed for
clarity. I have 333 vertices in my graph, and 4 edges. Do I correctly use
the edge_reverse property_map?
Regards,
Olivier
