Hi, you have come here because you clicked on a very old link, or a new link to a very old resource. The Finite State Machine paper you were after is no longer available.
That's the bad news.
The good news is that we have written a completely new state machine tutorial that is better, shinier and easier to read than the old one. You will
find it here:
New Finite State Machine tutorial
If your really want the old (1998) pdf article you can get it here.
