A tight lower bound for malicious online bipartite matching with limited recourse budget

We study one-sided online bipartite matching with recourse. In this setting, one side of a bipartite graph is known in advance, while vertices on the other side arrive online together with their incident edges. After each arrival, the algorithm must maintain a maximum-cardinality matching while minimizing the total num...

Online and Incremental Fractional Vertex Cover on Trees

This paper presents an $\frac{11}{6} \approx 1.83$-competitive algorithm for trees in the more general edge arrival model and gives a 1.5-competitive algorithm and provide a matching lower bound.
