Connectivity Oracles for Graphs Subject to Vertex Failures
SIAM Journal on Computing (SICOMP), Volume 49, Issue 6Pages 1363–1396https://doi.org/10.1137/17M1146610We introduce new data structures for answering connectivity queries in graphs subject to batched vertex failures. A deterministic structure processes a batch of $d\leq d_\star$ failed vertices in $\tilde{O}(d^3)$ time and thereafter answers connectivity ...

Bidimensionality and Kernels
SIAM Journal on Computing (SICOMP), Volume 49, Issue 6Pages 1397–1422https://doi.org/10.1137/16M1080264Bidimensionality theory was introduced by [E. D. Demaine et al., J. ACM, 52 (2005), pp. 866--893] as a tool to obtain subexponential time parameterized algorithms on H-minor-free graphs. In [E. D. Demaine and M. Hajiaghayi, Bidimensionality: New ...
