Succinct Graph Representations and Algorithmic Applications

Ahammed Ullah, Alex Pothen ยท 2026

We propose new graph representations that exploit dense local structure to improve time and space simultaneously. Given an undirected graph $G$, we define a dual clique cover (DCC) representation of $โ€ฆ

Simpler and Improved Replacement Path Coverings

Davide Bilo, Shiri Chechik, Keerti Choudhary, Sarel Cohen, Martin Schirneck ยท 2026

An important tool in the design of fault-tolerant graph data structures are $(L,f)$-replacement path coverings (RPCs). An RPC is a family $\mathcal{G}$ of subgraphs of a given graph $G$ such that, forโ€ฆ

Finite-Horizon First-Order Rank Profiles of Regular Languages

Madina Bazarova, Faruk Alpay ยท 2026

We introduce the finite-horizon first-order rank profile of a language $L \subseteq \Sigma^*$: the least quantifier rank needed by an $\mathrm{FO}[<]$ sentence to classify membership in $L$ correctly โ€ฆ

Path-Reporting Distance Oracles for Vertex-Labeled Graphs

Ofer Neiman, Alon Spector ยท 2026

Let $G=(V,E)$ be a weighted undirected graph, with $n$ vertices. A distance oracle is a data structure that can quickly answer distance queries, with some stretch factor. A seminal work of \cite{TZ01}โ€ฆ

On the hull of linearized polynomial codes

Daniele Bartoli, Giovanni Giuseppe Grimaldi, Pantelimon Stanica ยท 2026

Motivated by entanglement-assisted quantum error-correcting codes, where the hull dimension determines the number of required pre-shared entangled pairs, we study hulls of two families of $\mathbb{F}_โ€ฆ

Following the Eye-Tracking Evidence: Established Web-Search Assumptions Fail in Carousel Interfaces

Jingwei Kang, Maarten de Rijke, Harrie Oosterhuis ยท 2026

Carousel interfaces have been the de-facto standard for streaming media services for over a decade. Yet, there has been very little research into user behavior with such interfaces, which thus remainsโ€ฆ

On the Optimality of Network Topology Discovery in Single-Hop Bounded-Interference Networks

Tolunay Seyfi, Erfan Khadem, Fatemeh Afghah ยท 2026

We propose \emph{PRISM} (\textbf{Pseudorandom Residue-based Indexed Scheduling Method}), a deterministic topology-discovery framework for single-hop wireless networks with bounded interference. Each rโ€ฆ

A taxonomy for controlling (in)consistency

Marcelo E. Coniglio, Rafael Ongaratto ยท 2026

In this article, the hierarchy of LFIs L$_n^k$, Logics of Controlled Consistency (LCC), is introduced. Inspired by da Costa's original C$_n$ systems, this hierarchy can represent different degrees of โ€ฆ
