Q restricted rewrite system:
The TRS R consists of the following rules:
eq → true
eq → eq
eq → false
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:
Recursive path order with status [RPO].
Quasi-Precedence:
[eq, true] > false > [inf1, cons, 0, nil, s]
take2 > [inf1, cons, 0, nil, s]
length1 > [inf1, cons, 0, nil, s]
Status:
eq: multiset
true: multiset
false: multiset
inf1: multiset
cons: multiset
take2: multiset
0: multiset
nil: multiset
s: multiset
length1: multiset
With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly:
eq → false
inf(X) → cons
take(0, X) → nil
take(s, cons) → cons
length(nil) → 0
length(cons) → s

(3) QTRSRRRProof (EQUIVALENT transformation)
Used ordering:
Recursive path order with status [RPO].
Quasi-Precedence:
eq > true
Status:
eq: multiset
true: multiset
With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly:
eq → true
