Q is empty.

Using Dependency Pairs [1,13] we result in the following initial DP problem:

F3(0, 1, x) -> F3(s1(x), x, x)

The TRS R consists of the following rules:

g2(x, y) -> x

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.


F3(x, y, s1(z)) -> F3(0, 1, z)
The remaining pairs can at least be oriented weakly.

F3(0, 1, x) -> F3(s1(x), x, x)
Used ordering: Polynomial interpretation [21]:

POL(0) = 3   
POL(1) = 0   
POL(F3(x1, x2, x3)) = 2·x3   
POL(s1(x1)) = 1 + x1   

The following usable rules [14] were oriented: none
