WebApr 2, 2024 · Berge's Lemma states that a matching is maximum if and only if it has no augmenting path. An augmenting path is an acyclic (simple) path through a graph beginning and ending with an unmatched node. The edges along the path are alternately matched and unmatched. The number of edges in an augmenting path must always be odd. how long ago was february 21 2022
