Termination w.r.t. Q of the given QTRS could not be shown:

(0) Obligation:

Q restricted rewrite system:
The TRS R consists of the following rules:

f → f
g(b) → c
b → c

Q is empty.

(1) QTRSRRRProof (EQUIVALENT transformation)

Used ordering:
Recursive path order with status [RPO].
Precedence:

g₁ > c
b > c

Status:

c: multiset
f: multiset
g₁: multiset
b: multiset

With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly:

g(b) → c
b → c

(2) Obligation:

Q restricted rewrite system:
The TRS R consists of the following rules:

f → f

Q is empty.
