Re: [igraph] Memory error

[Ronquillo, Edgar Nahum]

Why would igraph ask for that big amount of GBs though? When I run a code with 
about half the vertices and edges it works perfect. It only takes about 700MB 
to fill up my list of edges and vertices and once I pass it to add_edges it 
takes another 300 or 400MB or so. It just doesn't make sense to me.

Yes, because it cannot allocate the rest. If it uses 1GB and igraph asks for 
(say) another 16GB, you'll get this error.

Sorry, what I meant is actual self-contained code that gives the error, not a 
textual description, I cannot really run that.
