Runtime Complexity of the query pattern
p()
w.r.t. the given Prolog program could be shown to be BOUNDS(O(1), O(1)).

(0) Obligation:

Clauses:

p :- thief(john).
thief(john).
thief(X) :- ','(thief(X), !).

Query: p()

(1) PrologToCdtProblemTransformerProof (UPPER BOUND (ID) transformation)

Built complexity over-approximating cdt problems from derivation graph.
