A deamortization approach for dynamic spanner and dynamic maximal matching

A Bernstein, S Forster, M Henzinger - ACM Transactions on Algorithms …, 2021 - dl.acm.org
Many dynamic graph algorithms have an amortized update time, rather than a stronger worst-
case guarantee. But amortized data structures are not suitable for real-time systems, where …

Graph sparsification, spectral sketches, and faster resistance computation via short cycle decompositions

Improved dynamic graph coloring

S Solomon, N Wein - ACM Transactions on Algorithms (TALG), 2020 - dl.acm.org
This article studies the fundamental problem of graph coloring in fully dynamic graphs. Since
the problem of computing an optimal coloring, or even approximating it to within n1-ε for any …

Nearly optimal vertex fault-tolerant spanners in optimal time: sequential, distributed, and parallel

We (nearly) settle the time complexity for computing vertex fault-tolerant (VFT) spanners with
optimal sparsity (up to polylogarithmic factors). VFT spanners are sparse subgraphs that …
