Description

graph-embed is a small library for (multi-level) graph partitioning and embedding.

Dependencies

linalgcpp OpenMP Plotly

Installation

To build the project:

  • mkdir build && cd build
  • cmake ../
  • make -j9

graph-embed

Graphs can be read in using linalgcpp. Once imported, partition the graph using partition::partition which takes a graph and a coarsening factor. This returns a hierarchy of partitions of the given graph, which each coarsen approximately by the given coarsening factor. These can be used to create a hierarchy of graphs. Finally, call partition::embed with the hierarchy of graphs, hierarchy of partitions, and desired dimension. This returns a vector of coordinates, indexed by the vertices of the graph.

See examples/embed.cpp and examples/embedder.cpp for an example.
