Graph Theory
[:days4/projects/: Other SAGE Days 4 Project]
- NetworkX: The following modules could be useful, and have not yet been wrapped: centrality, cliques, cluster, cores, hybrid, search, spectrum, threshold
- centrality, cliques, cluster, cores, search -- These are pretty standard graph theoretic programs, and should not take too long to wrap.
- spectrum -- This should probably not be wrapped, but instead mimicked, since sage's linear algebra is undoubtedly faster.
- hybrid, threshold -- These seem to be specialized programs that are closely related to the research areas of the NetworkX authors. It is unclear what to do with these.
- NICE: The nauty clone for computing automorphism groups of graphs, and computing isomorphism. It has been converted to Pyrex, but it could still stand much optimization.
- Wishlist from Chris Godsil: It would be great if we could complete the list this week.
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...
