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.


D11(*2(x, y)) -> D11(x)
D11(*2(x, y)) -> D11(y)
D11(+2(x, y)) -> D11(x)
D11(+2(x, y)) -> D11(y)
D11(-2(x, y)) -> D11(y)
D11(-2(x, y)) -> D11(x)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [21]:

POL(*2(x1, x2)) = 3 + x1 + 2·x2   
POL(+2(x1, x2)) = 3 + 2·x1 + 2·x2   
POL(-2(x1, x2)) = 3 + 2·x1 + 2·x2   
POL(D11(x1)) = 3·x1   

The following usable rules [14] were oriented: none
