Termination w.r.t. Q of the following Term Rewriting System could be proven:

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

f₁(a) -> f₁(b)
g₁(b) -> g₁(a)

Q is empty.

  ↳ Non-Overlap Check

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

f₁(a) -> f₁(b)
g₁(b) -> g₁(a)

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:

f₁(a) -> f₁(b)
g₁(b) -> g₁(a)

The set Q consists of the following terms:

f₁(a)
g₁(b)

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

G₁(b) -> G₁(a)
F₁(a) -> F₁(b)

The TRS R consists of the following rules:

f₁(a) -> f₁(b)
g₁(b) -> g₁(a)

The set Q consists of the following terms:

f₁(a)
g₁(b)

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