Multiple source nodes for DiHyperEdge

[Ethan Kuarez]

I've noticed that directed hyperedges can only have one source node. Is there a reason for this/is there a way to create a custom directed edge which will allow for multiple sources and multiple targets?

[Peter Empen]

Right, there is a lack of support for multiple sources for purely technical reasons on the traversing side.
Unfortunately, I don't see how to overcome it by any custom edge.
It is planned to addressed this issue in the first quarter of '17.

Hi Peter,

I'm hoping to use scala-graph to represent a hypergraph that also requires multiple source nodes for an edge. Do you know if this was ever implemented since this earlier conversation?

Thanks,

Mukul

Hi Makul,

not yet, unfortunately. But it is good to know there exists some interest in this feature.

Actually, I did start work on multiple-source hyperedges some time ago but I pushed the results aside due to lack of time and uncertainty about demand.

I may resume work, however. If so, it will take time since it is not an easy extension but rather a major retrofit of all edge types. Would you, or any other potential user, say it is still worth?

We were hoping to use scala-graph if it had that support, but since it doesn't we'll most likely write our own lightweight alternative for a prototype. As for whether it's worth it, that's completely up to you :).

Would love this feature--like Makul, we'll have to switch to an alternative in the meantime. Thanks!

Hi Melvin,

this is already done but need be shipped along with other changes so it is planned to be part of a 2.0 release.

I hope 2.0 may get ready late this year but that also depends on other contributors...
