% File : SWW095+1 : TPTP v8.2.0. Released v5.2.0.
% Domain : Software Verification
% Problem : Priority queue checker: lemma_check_characterization base
% Version : [Wie09] axioms : Especial.
% English : A proof obligation generated from a data structure verification
% problem. It comes from the verification of a procedure that
% removes an element from a sorted list and involves reasoning about
% reachability in graphs.
