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(a(a(b(x1)))) → A(x1)
A(a(a(b(x1)))) → A(a(a(x1)))
A(a(a(b(x1)))) → A(b(b(b(a(a(a(x1)))))))
A(a(a(b(x1)))) → A(a(x1))
The TRS R consists of the following rules:
a(x1) → x1
a(a(a(b(x1)))) → a(b(b(b(a(a(a(x1)))))))
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
