We use the reduction pair processor [13].


The following pairs can be oriented strictly and are deleted.


+12(c2(x, y), z) -> +12(y, z)
+12(x, c2(y, z)) -> +12(x, z)
+12(x, c2(y, z)) -> C2(y, +2(x, z))
+12(c2(x, y), z) -> C2(x, +2(y, z))
The remaining pairs can at least be oriented weakly.

C2(x, c2(y, z)) -> +12(x, y)
C2(x, c2(y, z)) -> C2(+2(x, y), z)
Used ordering: Polynomial Order [17,21] with Interpretation:

POL( +12(x1, x2) ) = x1 + x2


POL( c2(x1, x2) ) = x1 + x2 + 1


POL( C2(x1, x2) ) = max{0, x1 + x2 - 1}


POL( +2(x1, x2) ) = x1 + x2 + 1


POL( 1 ) = 0


POL( 6 ) = 0


POL( 7 ) = 0


POL( 5 ) = 0


POL( 8 ) = 0


POL( 3 ) = 0


POL( 9 ) = 0


POL( 4 ) = 0


POL( 0 ) = 0


POL( 2 ) = 0

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.


C2(x, c2(y, z)) -> C2(+2(x, y), z)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial Order [17,21] with Interpretation:

POL( C2(x1, x2) ) = x2


POL( c2(x1, x2) ) = x2 + 1



The following usable rules [14] were oriented: none

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