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:

g → h
c → d
h → g

Q is empty.

(1) QTRSRRRProof (EQUIVALENT transformation)

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

[g, h]
c > d

Status:

g: multiset
h: multiset
c: multiset
d: multiset

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

c → d

(2) Obligation:

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

g → h
h → g

Q is empty.
