Exactly Hittable Interval Graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
Given a set system $\mathcal{X} = \{\mathcal{U},\mathcal{S}\}$, where $\mathcal{U}$ is a set of elements and $\mathcal{S}$ is a set of subsets of $\mathcal{U}$, an exact hitting set $\mathcal{U}'$ is a subset of $\mathcal{U}$ such that each subset in ...

Testing Distributions of Huge Objects [PDF]

open access: yesTheoretiCS, 2023
We initiate a study of a new model of property testing that is a hybrid of testing properties of distributions and testing properties of strings. Specifically, the new model refers to testing properties of distributions, but these are distributions over ...

Fully Dynamic Connectivity in $O(\log n(\log\log n)^2)$ Amortized Expected Time [PDF]

open access: yesTheoretiCS, 2023
Dynamic connectivity is one of the most fundamental problems in dynamic graph algorithms. We present a randomized Las Vegas dynamic connectivity data structure with $O(\log n(\log\log n)^2)$ amortized expected update time and $O(\log n/\log\log\log n ...

Evacuating Robots from a Disk Using Face-to-Face Communication [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
Assume that two robots are located at the centre of a unit disk. Their goal is to evacuate from the disk through an exit at an unknown location on the boundary of the disk.

BDD-Based Algorithm for SCC Decomposition of Edge-Coloured Graphs [PDF]

open access: yesLogical Methods in Computer Science, 2022
Edge-coloured directed graphs provide an essential structure for modelling and analysis of complex systems arising in many scientific disciplines (e.g. feature-oriented systems, gene regulatory networks, etc.).

Parameterized Power Vertex Cover [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2018
We study a recently introduced generalization of the Vertex Cover (VC) problem, called Power Vertex Cover (PVC). In this problem, each edge of the input graph is supplied with a positive integer demand.

Brooks' Theorem in Graph Streams: A Single-Pass Semi-Streaming Algorithm for $\Delta$-Coloring [PDF]

open access: yesTheoretiCS, 2023
Every graph with maximum degree $\Delta$ can be colored with $(\Delta+1)$ colors using a simple greedy algorithm. Remarkably, recent work has shown that one can find such a coloring even in the semi-streaming model.

On-line algorithms for multiplication and division in real and complex numeration systems [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
A positional numeration system is given by a base and by a set of digits. The base is a real or complex number $\beta$ such that $|\beta|>1$, and the digit set $A$ is a finite set of digits including $0$. Thus a number can be seen as a finite or infinite

Multidimensional Binary Vector Assignment problem: standard, structural and above guarantee parameterizations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2017
In this article we focus on the parameterized complexity of the Multidimensional Binary Vector Assignment problem (called \BVA). An input of this problem is defined by $m$ disjoint sets $V^1, V^2, \dots, V^m$, each composed of $n$ binary vectors of size $

Fast Diameter Computation within Split Graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2021
When can we compute the diameter of a graph in quasi linear time? We address this question for the class of {\em split graphs}, that we observe to be the hardest instances for deciding whether the diameter is at most two.
