IGraph/M is the igraph interface for Mathematica
[Domination](https://en.wikipedia.org/wiki/Dominating_set) is one of the most central concepts in (algorithmic) graph theory, but there's not a lot of support for domination in IGraphM. As a start, to extend the family...
[According to the documentation](http://igraph.org/c/doc/igraph-Separators.html#igraph_minimum_size_separators), edge directions should be ignored. In reality, empty results are returned for directed graphs. ``` In[385]:= IGMinimumSeparators@CycleGraph[4, DirectedEdges -> True] Out[385]= {} In[386]:= IGMinimumSeparators@CycleGraph[4, DirectedEdges ->...

Suggestion by yode: `IGConnectNeighborhood[g, {3}]` should connect vertices at precisely distance 3 away (but not those that are at distance 2 away). Check: Can we do this using existing C/igraph...
**What is the feature or improvement you would like to see?** Since packed arrays can't contain `Infinity` or `Indeterminate`, these values are not currently supported in edge weights. This is...
The internal `vs[]` function does not detect that a vertex does not exist when passed a list of exiting vertices. This is because `VertexIndex` can take a list, even though...
**Describe the bug** The vertices are outside the region in `IGLatticeMesh` **To Reproduce** ``` Needs["IGraphM`"] len = 6; Show[Graphics[SSSTriangle[len, len, len]], IGMeshGraph@IGLatticeMesh["Triangular", SSSTriangle[len, len, len]]] ```  **Version information** The...
`IGGraphEditor` is one of my favorite functions. However, I've noticed that every time I make a change to the embedding and press `shift-enter`, many properties of the graph are lost,...
**Describe the bug** I would like to modify the graph embedding below (the original embedding is Tutte embedding). to make it more experiment-friendly. So I used the command `IGGraphEditor` but...
`IGDominatorTree` does not work on empty (edgeless) graph because empty graphs are treated as undirected by IGraph/M and `IGDominatorTree` requires directed ones.
