Q restricted rewrite system:
The TRS R consists of the following rules:

Begin(0(0(0(x)))) → Wait(Right1(x))
Begin(0(0(x))) → Wait(Right2(x))
Begin(0(x)) → Wait(Right3(x))
Begin(0(0(1(x)))) → Wait(Right4(x))
Begin(0(1(x))) → Wait(Right5(x))
Begin(1(x)) → Wait(Right6(x))
Right1(0(End(x))) → Left(0(0(1(1(End(x))))))
Right2(0(0(End(x)))) → Left(0(0(1(1(End(x))))))
Right3(0(0(0(End(x))))) → Left(0(0(1(1(End(x))))))
Right4(1(End(x))) → Left(0(0(1(0(End(x))))))
Right5(1(0(End(x)))) → Left(0(0(1(0(End(x))))))
Right6(1(0(0(End(x))))) → Left(0(0(1(0(End(x))))))
Right1(0(x)) → A0(Right1(x))
Right2(0(x)) → A0(Right2(x))
Right3(0(x)) → A0(Right3(x))
Right4(0(x)) → A0(Right4(x))

Right6(0(x)) → A0(Right6(x))
Right1(1(x)) → A1(Right1(x))
Right2(1(x)) → A1(Right2(x))
Right3(1(x)) → A1(Right3(x))
Right4(1(x)) → A1(Right4(x))
Right5(1(x)) → A1(Right5(x))
Right6(1(x)) → A1(Right6(x))
A0(Left(x)) → Left(0(x))
A1(Left(x)) → Left(1(x))
Wait(Left(x)) → Begin(x)
0(0(0(0(x)))) → 0(0(1(1(x))))

Q is empty.

(1) NonTerminationProof (COMPLETE transformation)

We used the non-termination processor [OPPELT08] to show that the SRS problem is infinite.
