Q restricted rewrite system:
The TRS R consists of the following rules:
*(x, *(y, z)) → *(*(x, y), z)
*(x, x) → x
Q is empty.
(1) DependencyPairsProof (EQUIVALENT transformation)
Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem.
(2) Obligation:
Q DP problem:
The TRS P consists of the following rules:
*1(x, *(y, z)) → *1(*(x, y), z)
*1(x, *(y, z)) → *1(x, y)
The TRS R consists of the following rules:
*(x, *(y, z)) → *(*(x, y), z)
*(x, x) → x
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
