(2) Obligation:

Clauses:

listA([]).

Query: listA(g)

(3) PrologToPiTRSProof (SOUND transformation)

We use the technique of [TOCL09]. With regard to the inferred argument filtering the predicates were used in the following modes:
Transforming Prolog into the following Term Rewriting System:
Pi-finite rewrite system:
The TRS R consists of the following rules:

listA_in_g([]) → listA_out_g([])

The argument filtering Pi contains the following mapping:
listA_in_g(x1)  =  listA_in_g(x1)
[]  =  []
listA_out_g(x1)  =  listA_out_g

Infinitary Constructor Rewriting Termination of PiTRS implies Termination of Prolog

(4) Obligation:

Pi-finite rewrite system:
The TRS R consists of the following rules:

listA_in_g([]) → listA_out_g([])

The argument filtering Pi contains the following mapping:
listA_in_g(x1)  =  listA_in_g(x1)
[]  =  []
listA_out_g(x1)  =  listA_out_g

(5) DependencyPairsProof (EQUIVALENT transformation)

Using Dependency Pairs [AG00,LOPSTR] we result in the following initial DP problem:
Pi DP problem:
P is empty.
The TRS R consists of the following rules:

listA_in_g([]) → listA_out_g([])

The argument filtering Pi contains the following mapping:
listA_in_g(x1)  =  listA_in_g(x1)
[]  =  []
listA_out_g(x1)  =  listA_out_g

We have to consider all (P,R,Pi)-chains

(6) Obligation:

Pi DP problem:
P is empty.
The TRS R consists of the following rules:

listA_in_g([]) → listA_out_g([])

The argument filtering Pi contains the following mapping:
listA_in_g(x1)  =  listA_in_g(x1)
[]  =  []
listA_out_g(x1)  =  listA_out_g

We have to consider all (P,R,Pi)-chains

(7) PisEmptyProof (EQUIVALENT transformation)

The TRS P is empty. Hence, there is no (P,R,Pi) chain.

(8) YES
