Q is empty.

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

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 strictly oriented and are deleted.


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

+12(*2(x, y), +2(*2(x, z), u)) -> +12(*2(x, +2(y, z)), u)
+12(x, +2(y, z)) -> +12(x, y)
+12(x, +2(y, z)) -> +12(+2(x, y), z)
Used ordering: Combined order from the following AFS and order.
+12(x1, x2)  =  x1
*2(x1, x2)  =  *1(x2)
+2(x1, x2)  =  x1

Lexicographic Path Order [19].

The following usable rules [14] were oriented:

+2(x, +2(y, z)) -> +2(+2(x, y), z)
+2(*2(x, y), +2(*2(x, z), u)) -> +2(*2(x, +2(y, z)), u)
+2(*2(x, y), +2(x, z)) -> *2(x, +2(y, z))
