Why does LightGraphs.betweenness_centrality() run so long

Asked 2021-Feb-19 at 19:58

When I try to calculate the betweenness_centrality() of my SimpleWeightedGraph with julia's LightGraphs package it runs indefinitely. It keeps on increasing it's RAM usage until at some point it crashes without an error message. Is the something wrong with my graph? Or what would be the best way to find the cause of this problem?

My graphs are not generated by LightGraphs but by another library, FlashWeave. I'm don't know if that matters...

The problem does not occur for unweighted SimpleGraph's or for the weighted graph I created in LightGraphs...

...

ANSWER

Answered 2021-Feb-19 at 19:58

Did you check if your graph contains negative weights? LightGraphs.betweenness_centrality() uses Dijkstra's shortest paths to calculate betweenness centrality, and thus expect non-negative weights.

LightGraphs.betweenness_centrality() doesn't check for illegal/nonsensical graphs. That's why it didn't throw an error. The issue is already reported here, but for now, check your own graphs if your not sure they are legal.

How to remove self-loops in Lightgraphs

Asked 2021-Jan-10 at 13:09

I am new to Julia and LightGraphs and I have been trying to find the most efficient way of detecting and removing self-loops. So far, the only way I have found is to iterate over all nodes in the Simplegraph, check whether it has a self-loop, and remove them. Is there any better way like using this combination in Python NetworkX: G.remove_edges_from(G.selfloop_edges())?

The way I am doing it right now:

...

ANSWER

Answered 2021-Jan-08 at 16:01

that's probably the best way to do it conditionally, but you can just call rem_edge!(G, node, node) without the has_edge() check - it returns a bool indicating whether the edge was removed so is safe to use if there's not an actual edge there.

QUESTION

Have trouble supplying Color Map to depth first search in boost graph library

Asked 2020-Dec-09 at 13:20

I am trying to use depth first search starting from a particular vertex. For that I need to supply a visitor and a color map.

If I don't supply a starting vertex then I don't need to supply a color map either and everything works fine. However, I didn't find a signature that would accept a starting vertex without requiring a color map.

I use C++ 17 (Embarcadero C++ Builder) Here is the code:

By wrapping your visitor in boost::visitor you are confusing with the named-parameter overload. Just pass the visitor:

how to create a subgraph with jgrapht

Asked 2020-Sep-24 at 17:01

I am using jgrapht in Java to work a network-based algorithm. I first read an adjacency list and then create jgrapht based graph. Now, given a subset of nodes called subNodes, I'd like to generate a sub graph. I am trying to use Subgraph class as shown at this link, however, I could not have it worked.

It seems you are referring to some old javadoc. Not sure why you are specifically using the 1.1.0. Here's an example using the 1.5 version of jgrapht:

I have made a JAR from SimpleGraph which I want to use it in a separat project.

Is there a way to include these into the JAR generation?

This is not possible. I cannot find the online source now, but I remember long ago wanting to create a planar graph (one in which the edges don't overlap)... and found an old ticket in the GraphViz project where they were discussing the feature. It was clear that this was an aging request that had been on hold for a long, long time.

Now, you can affect the distance between nodes, as I demonstrate in this answer. You might thy some of the ideas there to see if it can help your presentation.

I don't think you want an alternative to deepcopy, which is already doing what you want. It's just that heap memory allocation (as done by deepcopy) takes time. What you can do is make a single copy of g, then update that every time you'd need the deepcopy function, it might look like this
