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

ff
g(b) → c
bc

Q is empty.

(1) QTRSRRRProof (EQUIVALENT transformation)

Used ordering:
Recursive path order with status [RPO].
Precedence:
g1 > c
b > c

Status:
f: multiset
g1: multiset
b: multiset
c: multiset
With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly:

g(b) → c
bc
