Adaptive Massively Parallel Connectivity in Optimal Space
Proceedings of the 35th ACM Symposium on Parallelism in Algorithms and Architectures, 2023 We study the problem of finding connected components in the Adaptive Massively Parallel Computation (AMPC) model. We show that when we require the total space to be linear in the size of the input graph the problem can be solved in $O(\log^* n)$ rounds in forests (with high probability) and $2^{O(\log^* n)}$ expected rounds in general graphs.

Optimal Deterministic Massively Parallel Connectivity on Forests
, 2023 We show fast deterministic algorithms for fundamental problems on forests in the challenging low-space regime of the well-known Massive Parallel Computation (MPC) model. A recent breakthrough result by Coy and Czumaj [STOC'22] shows that, in this setting, it is possible to deterministically identify connected components on graphs in $O(\log D + \log ...

Transmitter CSI-Free RIS-Randomized CUMA for Extreme Massive Connectivity
IEEE Open Journal of the Communications SocietyThis paper proposes a transmitter channel state information (CSI)-free, massive connectivity scheme in the downlink that requires no optimization from the base station (BS) side. Inter-user interference is dealt with solely by the mobile users themselves,
