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

f2(g1(X), Y) -> f2(X, f2(g1(X), Y))

Q is empty.

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

F2(g1(X), Y) -> F2(X, f2(g1(X), Y))
F2(g1(X), Y) -> F2(g1(X), Y)

The TRS R consists of the following rules:

f2(g1(X), Y) -> f2(X, f2(g1(X), Y))

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

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

F2(g1(X), Y) -> F2(X, f2(g1(X), Y))
F2(g1(X), Y) -> F2(g1(X), Y)

The TRS R consists of the following rules:

f2(g1(X), Y) -> f2(X, f2(g1(X), Y))

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].


The following pairs can be oriented strictly and are deleted.


F2(g1(X), Y) -> F2(X, f2(g1(X), Y))
The remaining pairs can at least be oriented weakly.

F2(g1(X), Y) -> F2(g1(X), Y)
Used ordering: Polynomial interpretation [21]:

POL(F2(x1, x2)) = 2·x1   
POL(f2(x1, x2)) = 2   
POL(g1(x1)) = 2 + 2·x1   

The following usable rules [14] were oriented: none
