A sync bouncer counter is an informal class of Turing machines. A typical Turing machine in this class has the following behavior:
- It has both a bouncer and a counter on the tape, and the lowest digit of the counter is adjacent to the bouncer.
- Increment: the counter is increased by one, and the bouncer finishes a period.
- Overflow: when the counter overflows, the bouncer changes its structure (and change back before next overflow).
A Coq proof of a kind of typical behavior doesn't halt.
