(0) Obligation:

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

eqtrue
eqeq
eqfalse
inf(X) → cons
take(0, X) → nil
take(s, cons) → cons
length(nil) → 0
length(cons) → s

Q is empty.

(1) QTRSRRRProof (EQUIVALENT transformation)

Used ordering:
Lexicographic path order with status [LPO].
Quasi-Precedence:
[eq, true] > false > [inf1, cons, 0, nil, s]
take2 > [inf1, cons, 0, nil, s]
length1 > [inf1, cons, 0, nil, s]

Status:
eq: []
true: []
false: []
inf1: [1]
cons: []
take2: [1,2]
0: []
nil: []
s: []
length1: [1]

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

eqfalse
inf(X) → cons
take(0, X) → nil
take(s, cons) → cons
length(nil) → 0
length(cons) → s


(2) Obligation:

Q is empty.

(3) QTRSRRRProof (EQUIVALENT transformation)

Used ordering:
Lexicographic path order with status [LPO].
Quasi-Precedence:
eq > true

Status:
eq: []
true: []

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

eqtrue
