[igraph] Possible bug in python "find()" command?

[Nick Eubank]

Hi All,

I've been working with a relatively large graph, and have been having some trouble with the find() command. In particular, I'm finding the following two commands run at very, very different speeds (on a toy graph with 100,000 users and 1,000,000 nodes -- my actual graph has same problem, but is 100x larger). 

Blazing fast:

    for i in g.vs['name']:

        g.vs.find(i)

Very, very slow :

    for i in g.vs['name']:

        g.vs.find(name = i)

And yes, all names are strings, so this isn't the case one is querying by index and the other by names. 

Is there a reason why? My understanding was taht these were supposed to be equivalent (as suggested in the tutorial - http://igraph.org/python/doc/tutorial/tutorial.html ). I can work around, but wasn't sure if this was a bug or not, so thought I'd bring it up!

Thanks!

Nick
