Termination w.r.t. Q of the following Term Rewriting System could be proven:
Q restricted rewrite system:
The TRS R consists of the following rules:
*(x, +(y, z)) → +(*(x, y), *(x, z))
Q is empty.

Q restricted rewrite system:
The TRS R consists of the following rules:
*(x, +(y, z)) → +(*(x, y), *(x, z))
Q is empty.
Using Dependency Pairs [1,15] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:
*1(x, +(y, z)) → *1(x, y)
*1(x, +(y, z)) → *1(x, z)
The TRS R consists of the following rules:
*(x, +(y, z)) → +(*(x, y), *(x, z))
Q is empty.
We have to consider all minimal (P,Q,R)-chains.

Q DP problem:
The TRS P consists of the following rules:
*1(x, +(y, z)) → *1(x, y)
*1(x, +(y, z)) → *1(x, z)
The TRS R consists of the following rules:
*(x, +(y, z)) → +(*(x, y), *(x, z))
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].
The following pairs can be oriented strictly and are deleted.
*1(x, +(y, z)) → *1(x, y)
*1(x, +(y, z)) → *1(x, z)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:
POL(*1(x1, x2)) = (2)x_2
POL(+(x1, x2)) = 1/4 + (5/2)x_1 + (5/2)x_2
The value of delta used in the strict ordering is 1/2.
The following usable rules [17] were oriented:

Q DP problem:
P is empty.
The TRS R consists of the following rules:
*(x, +(y, z)) → +(*(x, y), *(x, z))
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.
