Q restricted rewrite system:
The TRS R consists of the following rules:
a(a(a(a(x)))) → b(a(a(b(x))))
b(a(b(x))) → a(b(a(x)))
B(a(b(a(a(a(x)))))) → A(b(b(a(a(b(x))))))
A(a(a(a(a(b(x)))))) → B(a(a(a(b(a(x))))))
B(a(b(b(x)))) → A(a(b(a(x))))
Q is empty.
We have reversed the following QTRS:
The set of rules R is
a(a(a(a(x)))) → b(a(a(b(x))))
b(a(b(x))) → a(b(a(x)))
a(a(a(b(a(B(x)))))) → b(a(a(b(b(A(x))))))
b(a(a(a(a(A(x)))))) → a(b(a(a(a(B(x))))))
b(b(a(B(x)))) → a(b(a(A(x))))
The set Q is empty.
We have obtained the following QTRS:
a(a(a(a(x)))) → b(a(a(b(x))))
b(a(b(x))) → a(b(a(x)))
B(a(b(a(a(a(x)))))) → A(b(b(a(a(b(x))))))
A(a(a(a(a(b(x)))))) → B(a(a(a(b(a(x))))))
B(a(b(b(x)))) → A(a(b(a(x))))
The set Q is empty.
