Yes. That's what I was thinking. I'm just not sure if the work would produce a significant enough gain. However, I can use a large random graph with lots of random property maps to get a baseline. I'll try it out and report back. On Wed, Jul 10, 2019, 10:37 PM Lietz, Haiko <Haiko.Lietz@gesis.org> wrote:
Hi Michael,
It seems that you're only interested in the relational structure and your nodes could be numbered in any way. If that is the case, you could create a graph object with as many nodes as your largest network and then use edge property maps to use a different (integer increasing) edge property for each network.
This technically works, but I don't know how efficient it is related to your old way of storing information.

Hi Haiko,
Every node/vertex is distinct, although they are often encoded as the same values in the data. For example, one graph might have three vertices (1, 2, 3) and two edges (1-2, 2-3). Another graph which is independent from the previous one could have four vertices (1, 2, 3, 4) and three edges (1-3, 1-2, 3-4).
Thanks, M

Hi Michael,
Are the nodes always the same or do they overlap somehow from graph to graph?

Hi all,
I just wanted to check what the most performance efficient way is to save lots of small graphs. I have around 120k small graphs (<10 vertices) that are currently being saved via pickle. However, I suspect that saving them as a single large graph or as multiple separate .gt files might be more performance efficient.
Thanks in advance. M _______________________________________________ graph-tool mailing list graph-tool@skewed.de https://lists.skewed.de/mailman/listinfo/graph-tool
