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:

f2(x, a) -> x
f2(x, g1(y)) -> f2(g1(x), y)

Q is empty.


QTRS
  ↳ Non-Overlap Check

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

f2(x, a) -> x
f2(x, g1(y)) -> f2(g1(x), y)

Q is empty.

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

The TRS R consists of the following rules:

f2(x, a) -> x
f2(x, g1(y)) -> f2(g1(x), y)

The set Q consists of the following terms:

f2(x0, a)

Q DP problem:
The TRS P consists of the following rules:

F2(x, g1(y)) -> F2(g1(x), y)

The TRS R consists of the following rules:

f2(x, a) -> x
f2(x, g1(y)) -> f2(g1(x), y)

The set Q consists of the following terms:

f2(x0, a)
f2(x0, g1(x1))

We have to consider all minimal (P,Q,R)-chains.
By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

F2(x, g1(y)) -> F2(g1(x), y)
Used argument filtering: F2(x1, x2)  =  x2
g1(x1)  =  g1(x1)
Used ordering: Quasi Precedence: trivial

Q DP problem:
P is empty.
The TRS R consists of the following rules:

f2(x, a) -> x
f2(x, g1(y)) -> f2(g1(x), y)

The set Q consists of the following terms:

f2(x0, a)
f2(x0, g1(x1))

We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
