Graph Theory

Participants: Emily Kirkman, Robert Miller, Craig Citro and David Roe
(done) Latex Graphs: Craig Citro & Robert Miller -- write an eps file to be included in LaTeX documents.
- (done) NetworkX 1: Expose these in SAGE: centrality, cliques, cluster, cores, search.
Also note significant updates to Generators class from wrapping NetworkX, (see the [http://www.sagemath.org:9001/graph_generators wiki] for pretty pictures).
- Graph Database: Update interface to sqlite database of all graphs with 8 or fewer vertices.
- Emily Kirkman is currently working on this.
Electrical Networks, Jim Morrow's REU: Graphs with boundary are already in sage, but there are probably some useful constructions for Jim's summer REU that are not implemented yet. Especially data structures, perhaps an ElectricalNetworks class. Look at the Dirichlet problem, graphs on surfaces and (circular) planar embeddings of graphs.

- Bipartite Class
- NetworkX 2:
- spectrum -- This should probably not be wrapped, but instead mimicked, since sage's linear algebra is undoubtedly faster.
- hybrid, threshold -- Figure out what these are?
