Determinacy proof of /tmp/tmpMQXLB4/short1.pl

Determinacy of the query pattern
p(a,a,a)
w.r.t. the given Prolog program could successfully be proven:

0 Prolog

↳1 BuiltinConflictTransformerProof (⇔, 0 ms)

↳2 Prolog

↳3 PrologDeterminacyProcessorProof (⇔, 82 ms)

↳4 YES

(0) Obligation:

Clauses:

p(X, Y, Z) :- ','(=(X, Y), ','(=(Z, 1), !)).
p(X, Y, Z) :- ','(=(Z, 1), ','(=(Y, X), p(X, Y, Z))).
=(X, X).

Query: p(a,a,a)

(1) BuiltinConflictTransformerProof (EQUIVALENT transformation)

Renamed defined predicates conflicting with built-in predicates [PROLOG].

(2) Obligation:

Clauses:

p(X, Y, Z) :- ','(user_defined_=(X, Y), ','(user_defined_=(Z, 1), !)).
p(X, Y, Z) :- ','(user_defined_=(Z, 1), ','(user_defined_=(Y, X), p(X, Y, Z))).
user_defined_=(X, X).

Query: p(a,a,a)

(3) PrologDeterminacyProcessorProof (EQUIVALENT transformation)

The root node satisfies the determinacy criterion.
