Comment:
Installation OK, doc OK for me, and running times/memory requirements more
than OK
Before applying the patch
{{{
sage: G = graphs.RandomGNM(1000,15000)
sage: %time G.diameter()
CPU times: user 23.71 s, sys: 0.00 s, total: 23.72 s
Wall time: 23.83 s
3
}}}
After:
{{{
sage: G = graphs.RandomGNM(1000,15000)
sage: %time G.diameter()
CPU times: user 0.11 s, sys: 0.00 s, total: 0.11 s
Wall time: 0.11 s
3
}}}
That's impressive !
I give positive review.
