Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By using the rule removal processor [15] with the following polynomial ordering [25], at least one Dependency Pair or term rewrite system rule of this QDP problem can be strictly oriented.
Strictly oriented dependency pairs:
B1.0(b.1(a.1(a.1(a.0(b.1(x)))))) → B1.0(b.1(x))
B1.0(b.1(a.1(a.1(a.0(b.0(x)))))) → B1.0(b.0(x))
Used ordering: POLO with Polynomial interpretation [25]:
POL(B.0(x1)) = x1
POL(B.1(x1)) = x1
POL(B1.0(x1)) = x1
POL(a.0(x1)) = 1 + x1
POL(a.1(x1)) = x1
POL(b.0(x1)) = x1
POL(b.1(x1)) = x1
