  • We study the online maximum matching problem with recourse in a model in which the edges are associated with a known recourse parameter $k$. An online algorithm for this problem has to maintain a valid matching while edges of the underlying graph are presented one after the other. At any moment the algorithm can decide to include an edge into the matching or to exclude it, under the restriction that at most $k$ actions per edge take place, where $k$ is typically a small constant. This problem… CONTINUE READING
