The TRS R consists of the following rules:

a(a(a(x))) → b(x)
b(b(a(x))) → a(b(a(a(b(x)))))
b(b(A(x))) → A(x)
a(a(b(b(A(x))))) → b(b(a(A(x))))
a(a(b(b(A(x))))) → b(b(A(x)))
b(b(b(b(A(x))))) → a(b(a(a(b(b(A(x)))))))
b(b(b(b(A(x))))) → a(b(a(a(b(b(a(A(x))))))))

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule B(b(a(b(A(x0))))) → B(b(b(a(A(x0))))) at position [0] we obtained the following new rules:

B(b(a(b(A(y0))))) → B(a(b(a(a(b(A(y0)))))))

Q DP problem:
The TRS P consists of the following rules:

B(b(b(b(A(x0))))) → A1(b(b(b(a(A(x0))))))
B(b(b(b(A(x0))))) → A1(b(b(b(A(x0)))))
A1(a(a(x))) → B(x)
B(b(b(b(A(x))))) → B(b(a(A(x))))
B(b(a(b(a(x0))))) → A1(b(a(a(a(b(a(a(b(x0)))))))))
B(b(a(b(b(b(A(x0))))))) → B(a(a(a(b(a(a(b(b(A(x0))))))))))
B(b(a(b(a(x0))))) → B(a(a(a(b(a(a(b(x0))))))))
B(b(a(b(b(b(A(x0))))))) → A1(a(b(a(a(b(b(a(A(x0)))))))))
B(b(a(b(b(b(A(x0))))))) → A1(b(a(a(a(b(a(a(b(b(A(x0)))))))))))
B(b(b(b(A(x0))))) → B(b(b(A(x0))))
B(b(b(b(A(y0))))) → A1(a(a(b(a(a(b(A(y0))))))))
B(b(a(b(b(b(A(x0))))))) → A1(b(a(a(a(b(a(a(b(b(a(A(x0))))))))))))
B(b(a(b(a(x0))))) → A1(a(b(a(a(b(x0))))))
B(b(a(x))) → B(x)
B(b(b(b(A(x))))) → A1(a(b(b(A(x)))))
B(b(a(x))) → A1(a(b(x)))
B(b(a(b(b(b(A(x0))))))) → A1(a(b(a(a(b(b(A(x0))))))))
B(b(b(b(A(x0))))) → B(b(b(a(A(x0)))))
B(b(b(b(A(y0))))) → A1(b(a(a(a(b(a(a(b(A(y0))))))))))
B(b(a(b(b(b(A(x0))))))) → B(a(a(a(b(a(a(b(b(a(A(x0)))))))))))
A1(a(b(b(A(x))))) → B(b(a(A(x))))
B(b(b(b(A(y0))))) → B(a(a(a(b(a(a(b(A(y0)))))))))

The TRS R consists of the following rules:

a(a(a(x))) → b(x)
b(b(a(x))) → a(b(a(a(b(x)))))
b(b(A(x))) → A(x)
a(a(b(b(A(x))))) → b(b(a(A(x))))
a(a(b(b(A(x))))) → b(b(A(x)))
b(b(b(b(A(x))))) → a(b(a(a(b(b(A(x)))))))
b(b(b(b(A(x))))) → a(b(a(a(b(b(a(A(x))))))))

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule B(b(b(b(A(x0))))) → A1(b(b(b(a(A(x0)))))) at position [0] we obtained the following new rules:

B(b(b(b(A(y0))))) → A1(b(a(b(a(a(b(A(y0))))))))

We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule B(b(b(b(A(x0))))) → A1(b(b(b(A(x0))))) at position [0] we obtained the following new rules:

B(b(b(b(A(x0))))) → A1(b(A(x0)))

Q DP problem:
The TRS P consists of the following rules:

A1(a(a(x))) → B(x)
B(b(b(b(A(x))))) → B(b(a(A(x))))
B(b(a(b(a(x0))))) → A1(b(a(a(a(b(a(a(b(x0)))))))))
B(b(a(b(b(b(A(x0))))))) → B(a(a(a(b(a(a(b(b(A(x0))))))))))
B(b(a(b(a(x0))))) → B(a(a(a(b(a(a(b(x0))))))))
B(b(a(b(b(b(A(x0))))))) → A1(a(b(a(a(b(b(a(A(x0)))))))))
B(b(a(b(b(b(A(x0))))))) → A1(b(a(a(a(b(a(a(b(b(A(x0)))))))))))
B(b(b(b(A(x0))))) → B(b(b(A(x0))))
B(b(b(b(A(y0))))) → A1(a(a(b(a(a(b(A(y0))))))))
B(b(a(b(b(b(A(x0))))))) → A1(b(a(a(a(b(a(a(b(b(a(A(x0))))))))))))
B(b(a(b(a(x0))))) → A1(a(b(a(a(b(x0))))))
B(b(a(x))) → B(x)
B(b(b(b(A(x))))) → A1(a(b(b(A(x)))))
B(b(a(x))) → A1(a(b(x)))
B(b(a(b(b(b(A(x0))))))) → A1(a(b(a(a(b(b(A(x0))))))))
B(b(b(b(A(x0))))) → B(b(b(a(A(x0)))))
B(b(b(b(A(y0))))) → A1(b(a(a(a(b(a(a(b(A(y0))))))))))
B(b(a(b(b(b(A(x0))))))) → B(a(a(a(b(a(a(b(b(a(A(x0)))))))))))
A1(a(b(b(A(x))))) → B(b(a(A(x))))
B(b(b(b(A(y0))))) → B(a(a(a(b(a(a(b(A(y0)))))))))

The TRS R consists of the following rules:

a(a(a(x))) → b(x)
b(b(a(x))) → a(b(a(a(b(x)))))
b(b(A(x))) → A(x)
a(a(b(b(A(x))))) → b(b(a(A(x))))
a(a(b(b(A(x))))) → b(b(A(x)))
b(b(b(b(A(x))))) → a(b(a(a(b(b(A(x)))))))
b(b(b(b(A(x))))) → a(b(a(a(b(b(a(A(x))))))))

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule B(b(b(b(A(x0))))) → B(b(b(a(A(x0))))) at position [0] we obtained the following new rules:

B(b(b(b(A(y0))))) → B(a(b(a(a(b(A(y0)))))))

Q DP problem:
The TRS P consists of the following rules:

A1(a(a(x))) → B(x)
B(b(b(b(A(x))))) → B(b(a(A(x))))
B(b(a(b(a(x0))))) → A1(b(a(a(a(b(a(a(b(x0)))))))))
B(b(a(b(b(b(A(x0))))))) → B(a(a(a(b(a(a(b(b(A(x0))))))))))
B(b(a(b(a(x0))))) → B(a(a(a(b(a(a(b(x0))))))))
B(b(a(b(b(b(A(x0))))))) → A1(a(b(a(a(b(b(a(A(x0)))))))))
B(b(a(b(b(b(A(x0))))))) → A1(b(a(a(a(b(a(a(b(b(A(x0)))))))))))
B(b(b(b(A(x0))))) → B(b(b(A(x0))))
B(b(b(b(A(y0))))) → A1(a(a(b(a(a(b(A(y0))))))))
B(b(a(b(b(b(A(x0))))))) → A1(b(a(a(a(b(a(a(b(b(a(A(x0))))))))))))
B(b(a(b(a(x0))))) → A1(a(b(a(a(b(x0))))))
B(b(a(x))) → B(x)
B(b(b(b(A(x))))) → A1(a(b(b(A(x)))))
B(b(a(x))) → A1(a(b(x)))
B(b(a(b(b(b(A(x0))))))) → A1(a(b(a(a(b(b(A(x0))))))))
B(b(b(b(A(y0))))) → A1(b(a(a(a(b(a(a(b(A(y0))))))))))
B(b(a(b(b(b(A(x0))))))) → B(a(a(a(b(a(a(b(b(a(A(x0)))))))))))
A1(a(b(b(A(x))))) → B(b(a(A(x))))
B(b(b(b(A(y0))))) → B(a(a(a(b(a(a(b(A(y0)))))))))

The TRS R consists of the following rules:

a(a(a(x))) → b(x)
b(b(a(x))) → a(b(a(a(b(x)))))
b(b(A(x))) → A(x)
a(a(b(b(A(x))))) → b(b(a(A(x))))
a(a(b(b(A(x))))) → b(b(A(x)))
b(b(b(b(A(x))))) → a(b(a(a(b(b(A(x)))))))
b(b(b(b(A(x))))) → a(b(a(a(b(b(a(A(x))))))))

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule B(b(b(b(A(x0))))) → B(b(b(A(x0)))) at position [0] we obtained the following new rules:

B(b(b(b(A(x0))))) → B(A(x0))

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We have reversed the following QTRS:
The set of rules R is

a(a(a(x1))) → b(x1)
a(b(b(x1))) → b(a(a(b(a(x1)))))

The set Q is empty.
We have obtained the following QTRS:

a(a(a(x))) → b(x)
b(b(a(x))) → a(b(a(a(b(x)))))

The set Q is empty.
