Vertex to perform graph coloring on simple, connected, undirected graphs and
related test.
------------------------------------------------------------------------------------------
Key: GIRAPH-157
URL: https://issues.apache.org/jira/browse/GIRAPH-157
Project: Giraph
Issue Type: Test
Components: examples, test
Affects Versions: 0.2.0
Reporter: Eli Reisman
Assignee: Eli Reisman
Priority: Trivial
Hi. I am attempting to learn the Hadoop and Giraph codebases and wanted to
write a simple client application for Giraph to help me learn the ins and outs
of it. This is a simple unit test and vertex modeled after the
ConnectedComponentsVertex and related test. The vertex test runs whenever you
run the "mvn test" or "mvn verify" suite of tests. When finished processing,
each vertex will have an integer value that is its color.
This is a pretty simple implementation, and although I have tested it on a
number of small graphs of varied trickiness and it seems to rapidly arrive at a
minimal coloring, its hard (for me at least) to guess which possible coloring
it will arrive at and I have no idea how it will do on really big graphs yet
without finding some more pre-colored larger test graphs to try it on. Ideas
anyone?
Anyway, it was fun to put this together, and I'd be happy to improve it or
receive some help or advice to further the cause. Thanks again, I am hoping
this will be the first of many (hopefully more useful) contributions!
Eli
