Distributed half-integral matching and beyond
Theoretical Computer Science (TCSC), Volume 982, Issue Chttps://doi.org/10.1016/j.tcs.2023.114278AbstractBy prior work, it is known that any distributed graph algorithm that finds a maximal matching requires Ω ( log ⁎ n ) communication rounds, while it is possible to find a maximal fractional matching in O ( 1 ) rounds in bounded-degree graphs. ...

Distributed graph problems through an automata-theoretic lens
Theoretical Computer Science (TCSC), Volume 951, Issue Chttps://doi.org/10.1016/j.tcs.2023.113710AbstractThe locality of a graph problem is the smallest distance T such that each node can choose its own part of the solution based on its radius-T neighborhood. In many settings, a graph problem can be solved efficiently with a distributed ...
