Tight Bounds for Low-Error Frequency Moment Estimation and the Power of Multiple Passes

Naomi Green-Maimon, Or Zamir · 2025

Estimating the second frequency moment $F_2$ of a data stream up to a $(1 \pm \varepsilon)$ factor is a central problem in the streaming literature. For errors $\varepsilon > \Omega(1/\sqrt{n})$, the …

Counting Distinct Square Substrings in Sublinear Time

Panagiotis Charalampopoulos, Manal Mohamed, Jakub Radoszewski, Wojciech Rytter, Tomasz Walen, Wiktor Zuba · 2025

We show that the number of distinct squares in a packed string of length $n$ over an alphabet of size $\sigma$ can be computed in $O(n/\log_\sigma n)$ time in the word-RAM model. This paper is the fir…

String Consensus Problems with Swaps and Substitutions

Esteban Gabory, Laurent Bulteau, Gabriele Fici, Hilde Verbeek · 2025

String consensus problems aim at finding a string that minimizes some given distance with respect to an input set of strings. In particular, in the Closest string problem, we are given a set of string…

Minimality and computability of languages of G-shifts

Djamel Eddine Amir, Benjamin Hellouin de Menibus · 2025

Motivated by the notion of strong computable type for sets in computable analysis, we define the notion of strong computable type for $G$-shifts, where $G$ is a finitely generated group with decidable…

MD-ViSCo: A Unified Model for Multi-Directional Vital Sign Waveform Conversion

Franck Meyer, Kyunghoon Hur, Edward Choi · 2025

Despite the remarkable progress of deep-learning methods generating a target vital sign waveform from a source vital sign waveform, most existing models are designed exclusively for a specific source-…

An Almost Tight Lower Bound for Plurality Consensus with Undecided State Dynamics in the Population Protocol Model

Antoine El-Hayek, Robert Elsasser, Stefan Schmid · 2025

We revisit the majority problem in the population protocol communication model, as first studied by Angluin et al. (Distributed Computing 2008). We consider a more general version of this problem know…

Local Computation Algorithms for Knapsack: impossibility results, and how to avoid them

Clement L. Canonne, Yun Li, Seeun William Umboh · 2025

Local Computation Algorithms (LCA), as introduced by Rubinfeld, Tamir, Vardi, and Xie (2011), are a type of ultra-efficient algorithms which, given access to a (large) input for a given computational …

On the existence of EFX allocations in multigraphs

Alkmini Sgouritsa, Minas Marios Sotiriou · 2025

We study the problem of "fairly" dividing indivisible goods to several agents that have valuation set functions over the sets of goods. As fair we consider the allocations that are envy-free up to any…

Near-Optimal Dimension Reduction for Facility Location

Lingxiao Huang, Shaofeng H.-C. Jiang, Robert Krauthgamer, Di Yue · 2024

Oblivious dimension reduction, \`{a} la the Johnson-Lindenstrauss (JL) Lemma, is a fundamental approach for processing high-dimensional data. We study this approach for Uniform Facility Location (UFL)…

Faster two-dimensional pattern matching with $k$ mismatches

Jonas Ellert, Pawe{l} Gawrychowski, Adam Gorkiewicz, Tatiana Starikovskaya · 2024

The classical pattern matching asks for locating all occurrences of one string, called the pattern, in another, called the text, where a string is simply a sequence of characters. Due to the potential…

Faster and simpler online/sliding rightmost Lempel-Ziv factorizations

Wataru Sumiyoshi, Takuya Mieno, Shunsuke Inenaga · 2024

We tackle the problems of computing the rightmost variant of the Lempel-Ziv factorizations in the online/sliding model. Previous best bounds for this problem are O(n log n) time with O(n) space, due t…
