Towards Multi-Pass Streaming Lower Bounds for Optimal Approximation of Max-Cut

L Chen, G Kol, D Paramonov, RR Saxena, Z Song… - Proceedings of the 2023 …, 2023 - SIAM
We consider the Max-Cut problem, asking how much space is needed by a streaming
algorithm in order to estimate the value of the maximum cut in a graph. This problem has …

Oblivious algorithms for the Max-AND Problem

NG Singer - arXiv preprint arXiv:2305.04438, 2023 - arxiv.org
Motivated by recent works on streaming algorithms for constraint satisfaction problems
(CSPs), we define and analyze oblivious algorithms for the Max-$ k $ AND problem. This …

Streaming complexity of CSPs with randomly ordered constraints

RR Saxena, N Singer, M Sudan, S Velusamy - … of the 2023 Annual ACM-SIAM …, 2023 - SIAM
We initiate a study of the streaming complexity of constraint satisfaction problems (CSPs)
when the constraints arrive in a random order. We show that there exists a CSP, namely Max …

Improved streaming algorithms for Maximum Directed Cut via smoothed snapshots

RR Saxena, NG Singer, M Sudan… - 2023 IEEE 64th …, 2023 - ieeexplore.ieee.org
We give an O(n)-space single-pass 0.483-approximation streaming algorithm for estimating
the maximum directed cut size (Max-DICUT) in a directed graph on n vertices. This improves …

Streaming approximation resistance of every ordering CSP

NG Singer, M Sudan, S Velusamy - arXiv preprint arXiv:2105.01782, 2021 - arxiv.org
An ordering constraint satisfaction problem (OCSP) is defined by a family $\mathcal {F} $ of
predicates mapping permutations on $\{1,\ldots, k\} $ to $\{0, 1\} $. An instance of Max-OCSP …

The quantum and classical streaming complexity of quantum and classical max-cut

J Kallaugher, O Parekh - 2022 IEEE 63rd Annual Symposium …, 2022 - ieeexplore.ieee.org
We investigate the space complexity of two graph streaming problems: MAX-CUT and its
quantum analogue, QUANTUM MAX-CUT. Previous work by Kapralov and Krachun [STOC …

Streaming and Sketching Complexity of CSPs: A Survey

M Sudan - arXiv preprint arXiv:2205.02744, 2022 - arxiv.org
In this survey we describe progress over the last decade or so in understanding the
complexity of solving constraint satisfaction problems (CSPs) approximately in the streaming …

Sketching approximability of all finite CSPs

CN Chou, A Golovnev, M Sudan, S Velusamy - Journal of the ACM, 2024 - dl.acm.org
A constraint satisfaction problem (CSP),, is specified by a finite set of constraints for positive
integers q and k. An instance of the problem on n variables is given by m applications of …

Streaming Algorithms via Local Algorithms for Maximum Directed Cut

RR Saxena, NG Singer, M Sudan, S Velusamy - Proceedings of the 2025 …, 2025 - SIAM
We explore the use of local algorithms in the design of streaming algorithms for the
Maximum Directed Cut problem. Specifically, building on the local algorithm of (Buchbinder …
