Distributed Symmetry-Breaking Algorithms for Congested Cliques

Abstract: The Congested Clique is a distributed-computing model for single-hop networks with restricted bandwidth that has been very intensively studied recently. It models a network by an n-vertex graph in which any pair of vertices can communicate one with another by transmitting O(log n) bits in each round. Various problems have been studied in this setting, but for some of them the best-known results are those for general networks. For other problems, the results for Congested Cliques are better than on general netw… Show more

“…In this paper, our new distributed result is an improvement for coloring in the CONGESTED-CLIQUE model. It is worth noting that the CONGESTED-CLIQUE model has been receiving extensive attention recently, see e.g., [PST11, DLP12, BHP12, Len13, DKO14, Nan14, HPS14, HP15, CHKK + 16, HPP + 15, BKKL17, Gal16, CLT18, Gha16, Gha17, GGK + 18, PS18,Par18,BK18].…”

“…Parameterized distributed algorithms have appeared implicitly in many of the above-mentioned subgraph detection works, and recently Ben-Basat et al [10] and Siebertz and Vigny [43] have explicitly studied aspects of distributed parameterized complexity. In terms of structural parameters, maximum degree is a standard parameter in distributed setting, and algorithms parameterized degeneracy has been studied for various problems and models [7,9,31]. Recently, Li [35] has show that the treewidth of the input graph can be approximated in Õ(D) rounds in CONGEST, and many classical optimization problems that are fixed-parameter tractable wrt.…”

“…Via a reduction to the maximal independent set (MIS) problem, they gave a (Δ + 1)-coloring algorithm that runs in (log Δ) rounds provided that Δ = ( 1/3 ). Parter [18] showed a deterministic (Δ + 1)-coloring in (log Δ) rounds, that works for any value of Δ. Barenboim and Khazanov [2] presented improved deterministic local algorithms as a function of the graph's arboricity. Finally, concurrently with our work, Bamberger et al [1] give (deg +1)-list coloring algorithms requiring (log Δ log log Δ) rounds in CONGESTED CLIQUE, (log 2 Δ) in linear-space MPC, and (log 2 Δ + log ) in low-space MPC.…”
