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

Begin(a(b(b(x)))) → Wait(Right1(x))
Begin(b(b(x))) → Wait(Right2(x))
Begin(b(x)) → Wait(Right3(x))
Begin(c(x)) → Wait(Right4(x))
Begin(b(x)) → Wait(Right5(x))
Right1(a(End(x))) → Left(b(b(b(a(a(a(End(x))))))))
Right2(a(a(End(x)))) → Left(b(b(b(a(a(a(End(x))))))))
Right3(a(a(b(End(x))))) → Left(b(b(b(a(a(a(End(x))))))))
Right4(a(End(x))) → Left(c(a(End(x))))
Right5(c(End(x))) → Left(b(c(End(x))))
Right1(a(x)) → Aa(Right1(x))
Right2(a(x)) → Aa(Right2(x))
Right3(a(x)) → Aa(Right3(x))
Right4(a(x)) → Aa(Right4(x))
Right5(a(x)) → Aa(Right5(x))
Right1(b(x)) → Ab(Right1(x))
Right2(b(x)) → Ab(Right2(x))
Right3(b(x)) → Ab(Right3(x))
Right4(b(x)) → Ab(Right4(x))
Right5(b(x)) → Ab(Right5(x))
Right1(c(x)) → Ac(Right1(x))
Right2(c(x)) → Ac(Right2(x))
Right3(c(x)) → Ac(Right3(x))
Right4(c(x)) → Ac(Right4(x))
Right5(c(x)) → Ac(Right5(x))
Aa(Left(x)) → Left(a(x))
Ab(Left(x)) → Left(b(x))
Ac(Left(x)) → Left(c(x))
Wait(Left(x)) → Begin(x)
a(a(b(b(x)))) → b(b(b(a(a(a(x))))))
a(c(x)) → c(a(x))
c(b(x)) → b(c(x))

Q is empty.

(1) NonTerminationProof (COMPLETE transformation)

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

Found the self-embedding DerivationStructure:
Wait Left b c End → Wait Left b c End

Wait Left b c End → Wait Left b c End
by OverlapClosure OC 2
Wait Left b → Wait Right5
by OverlapClosure OC 2
Wait Left → Begin
by original rule (OC 1)
Begin b → Wait Right5
by original rule (OC 1)
Right5 c End → Left b c End
by original rule (OC 1)

(2) NO
