Original question and givens

Use complete finite unique vertices=[c0, l0_0, l0_1, l0_2, l0_3, l0_4, l0_5, l0_6, l0_7, l0_8, l0_9, l0_10], loop-free simple undirected edges=[[c0, l0_0], [c0, l0_1], [c0, l0_2], [c0, l0_3], [c0, l0_4], [c0, l0_5], [c0, l0_6], [c0, l0_7], [c0, l0_8], [c0, l0_9], [c0, l0_10]] and unique candidate subset=[l0_0, l0_1, l0_2, l0_3, l0_4, l0_5, l0_6, l0_7, l0_8, l0_9, l0_10]. Edges normalize to sorted unordered pairs and are duplicate-free. A cover selects at least one endpoint of every edge; isolated vertices need not be selected. Give (candidate, deletion_rows, inclusion_minimal, minimum_size, minimum, minimality_tests_agree, certificate).

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.

Conditions: none

Count covers by size over all2^n subsets.Zero counts at smaller sizes give a lower bound and the explicit witness attains it.By superset monotonicity,any proper-subset cover would make some single deletion a cover,so deletion tests characterize inclusion-minimality,not minimum cardinality.The last flag compares two Booleans;bothFalse may agree.
