Q restricted rewrite system:
The TRS R consists of the following rules:
g(X) → h(X)
c → d
h(d) → g(c)
Q is empty.
(1) AAECC Innermost (EQUIVALENT transformation)
We have applied [NOC,AAECCNOC] to switch to innermost. The TRS R 1 is
c → d
The TRS R 2 is
g(X) → h(X)
h(d) → g(c)
The signature Sigma is {
g,
h}
(2) Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:
g(X) → h(X)
c → d
h(d) → g(c)
The set Q consists of the following terms:
g(x0)
c
h(d)
(3) DependencyPairsProof (EQUIVALENT transformation)
Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem.
(4) Obligation:
Q DP problem:
The TRS P consists of the following rules:
G(X) → H(X)
H(d) → G(c)
H(d) → C
The TRS R consists of the following rules:
g(X) → h(X)
c → d
h(d) → g(c)
The set Q consists of the following terms:
g(x0)
c
h(d)
We have to consider all minimal (P,Q,R)-chains.
(5) DependencyGraphProof (EQUIVALENT transformation)
The approximation of the Dependency Graph [LPAR04,FROCOS05,EDGSTAR] contains 1 SCC with 1 less node.
