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(x1)
b(a(c(x1))) → c(c(a(a(x1))))
c(x1) → b(x1)
Q is empty.

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