Thanks

I did some work on this back in the early 90's -- the results were
published in 1997 in IEEE Transactions on Computers if that's recent
enough for you. You can also get a copy here:

I haven't really looked at this stuff in a while, so I'm afraid I
don't know what newer results might be out there....
