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

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

p3(m, n, s1(r)) -> p3(m, r, n)
p3(m, s1(n), 0) -> p3(0, n, m)
p3(m, 0, 0) -> m

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:

P3(m, n, s1(r)) -> P3(m, r, n)
P3(m, s1(n), 0) -> P3(0, n, m)

The TRS R consists of the following rules:

p3(m, n, s1(r)) -> p3(m, r, n)
p3(m, s1(n), 0) -> p3(0, n, m)
p3(m, 0, 0) -> m

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

The TRS P consists of the following rules:

P3(m, n, s1(r)) -> P3(m, r, n)
P3(m, s1(n), 0) -> P3(0, n, m)

The TRS R consists of the following rules:

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.


P3(m, n, s1(r)) -> P3(m, r, n)
P3(m, s1(n), 0) -> P3(0, n, m)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [21]:

POL(0) = 2   
POL(P3(x1, x2, x3)) = 2·x1 + x2 + x3   
POL(s1(x1)) = 3 + x1   

The following usable rules [14] were oriented: none
