Re: [igraph] infomap unresponsive? on large graph in R env

[Peter Smits]

Hi,

Something you might consider is using the Map Equation software provided by the developers. http://mapequation.org/code.html

I've found it is very very fast, allowing for multiple processors. You just need the graph in question in pajek format, which igraph can export. After this, you can bring the results back into R. It could be automated easily with some shell scripting.

Cheers,

Peter

Hi,

has anyone any info on a memory limit of igraph which I may have missed in the documentation?
I'd really like to use igraph's implementation of InfoMap but run into the problem described below.

Thanks,
Alexander
