  Modifying Gibbs Sampling to Avoid Self Transitions

The algorithms described in the paper are implemented (in R) in the
file methods.r.  Various checks for validity of these methods are
done in check-all.r.

The experimental runs reported in the paper can be reproduced with the
run-potts-8x8, run-potts-5x5, run-mix, run-beliefnet, and run-other
shell scripts.  These runs take a long time - several days, in total.
The outputs of these runs are in the sub-directory 'runs', except for
the saved R workspaces, which would be quite large.

Checking out the small-runs branch of this repository will switch to
smaller runs (1/100 the length of the full runs), which take only
about a half hour or less for each shell script.  Of course, the
asymptotic variance estimates are then much noisier.  The results of
these smaller runs are in the 'runs' sub-directory when the small-runs
branch is checked out.
