(3) PrologToPiTRSProof (SOUND transformation)

We use the technique of [LOPSTR]. With regard to the inferred argument filtering the predicates were used in the following modes:
in1_in: (f,b) (b,b)
in10_in: (b)
p40_in: (f,b,b) (b,b,b)
less42_in: (f,b) (b,b)
p53_in: (b,b,b) (b,f,b)
less54_in: (b,b) (b,f)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

• LESS54_IN_GA(s(T147)) → LESS54_IN_GA(T147)
  The graph contains the following edges 1 > 1

(17) UsableRulesProof (EQUIVALENT transformation)

For (infinitary) constructor rewriting [LOPSTR] we can delete all non-usable rules from R.

(18) Obligation:

Pi DP problem:
The TRS P consists of the following rules:

LESS54_IN_GG(s(T147), s(T149)) → LESS54_IN_GG(T147, T149)

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

(19) PiDPToQDPProof (EQUIVALENT transformation)

Transforming (infinitary) constructor rewriting Pi-DP problem [LOPSTR] into ordinary QDP problem [LPAR04] by application of Pi.

(20) Obligation:

Q DP problem:
The TRS P consists of the following rules:

LESS54_IN_GG(s(T147), s(T149)) → LESS54_IN_GG(T147, T149)

R is empty.
Q is empty.
We have to consider all (P,Q,R)-chains.

(21) QDPSizeChangeProof (EQUIVALENT transformation)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

• LESS54_IN_GG(s(T147), s(T149)) → LESS54_IN_GG(T147, T149)
  The graph contains the following edges 1 > 1, 2 > 2

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

• P53_IN_GAG(T129, T131) → U9_GAG(T129, T131, less54_in_ga(T129))
  The graph contains the following edges 1 >= 1, 2 >= 2

• U9_GAG(T129, T131, less54_out_ga(T129)) → IN1_IN_AG(T131)
  The graph contains the following edges 2 >= 1
