Dear Craig,

However, on 15 Dec 2003, you wrote:

And in your 16 Dec 2003 mail, you claimed that "secret internal
relettering (or renaming or renumbering) inside of the algorithm
affects who the winner is." Thus, on the one side you call the
Floyd algorithm "defective" and claim that the result of the
Floyd algorithm depends on the lettering and on the other side
you write that you "did not claim that the Floyd algorithm
'doesn't work'".
