Termination w.r.t. Q of the following Term Rewriting System could not be shown:
Q restricted rewrite system:
The TRS R consists of the following rules:
a(x1) → x1
a(x1) → b(c(b(x1)))
a(b(b(x1))) → b(b(a(a(x1))))
Q is empty.

Q restricted rewrite system:
The TRS R consists of the following rules:
a(x1) → x1
a(x1) → b(c(b(x1)))
a(b(b(x1))) → b(b(a(a(x1))))
Q is empty.
Using Dependency Pairs [1,15] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:
A(b(b(x1))) → A(x1)
A(b(b(x1))) → A(a(x1))
The TRS R consists of the following rules:
a(x1) → x1
a(x1) → b(c(b(x1)))
a(b(b(x1))) → b(b(a(a(x1))))
Q is empty.
We have to consider all minimal (P,Q,R)-chains.

We have to consider all minimal (P,Q,R)-chains.
We have reversed the following QTRS:
The set of rules R is
a(x1) → x1
a(x1) → b(c(b(x1)))
a(b(b(x1))) → b(b(a(a(x1))))
The set Q is empty.
We have obtained the following QTRS:
a(x) → x
a(x) → b(c(b(x)))
b(b(a(x))) → a(a(b(b(x))))
The set Q is empty.
