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:

a₁(b₁(x)) -> b₁(b₁(a₁(a₁(x))))

Q is empty.

  ↳ Non-Overlap Check

Q restricted rewrite system:
The TRS R consists of the following rules:

a₁(b₁(x)) -> b₁(b₁(a₁(a₁(x))))

Q is empty.

The TRS is non-overlapping. Hence, we can switch to innermost.

Q restricted rewrite system:
The TRS R consists of the following rules:

a₁(b₁(x)) -> b₁(b₁(a₁(a₁(x))))

The set Q consists of the following terms:

a₁(b₁(x0))

Using Dependency Pairs [1,13] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:

A₁(b₁(x)) -> A₁(a₁(x))
A₁(b₁(x)) -> A₁(x)

The TRS R consists of the following rules:

a₁(b₁(x)) -> b₁(b₁(a₁(a₁(x))))

The set Q consists of the following terms:

a₁(b₁(x0))

We have to consider all minimal (P,Q,R)-chains.
