A Markov chain algorithm for compression in self-organizing particle systems

S Cannon, JJ Daymude, D Randall… - Proceedings of the 2016 …, 2016 - dl.acm.org
We consider programmable matter as a collection of simple computational elements (or
particles) with limited (constant-size) memory that self-organize to solve system-wide …

Gathering in dynamic rings

GA Di Luna, P Flocchini, L Pagli, G Prencipe… - Theoretical Computer …, 2020 - Elsevier
The gathering (or multi-agent rendezvous) problem requires a set of mobile agents,
arbitrarily positioned at different nodes of a network to group within finite time at the same …

Graph explorations with mobile agents

S Das - Distributed Computing by Mobile Entities: Current …, 2019 - Springer
The basic primitive for a mobile agent is the ability to visit all the nodes of the graph in a
systematic manner. This chapter considers the exploration of unknown graphs in full detail …

Locating a black hole in a dynamic ring

GA Di Luna, P Flocchini, G Prencipe… - Journal of Parallel and …, 2025 - Elsevier
In networked environments supporting mobile agents, a pressing problem is the presence of
network sites harmful for the agents. In this paper we consider the danger posed by a node …

Searching for black holes in subways

P Flocchini, M Kellett, PC Mason, N Santoro - Theory of Computing …, 2012 - Springer
Current mobile agent algorithms for map** faults in computer networks assume that the
network is static. However, for large classes of highly dynamic networks (eg, wireless mobile …

[HTML][HTML] Gathering of robots in a ring with mobile faults

S Das, R Focardi, FL Luccio, E Markou… - Theoretical Computer …, 2019 - Elsevier
This paper studies the well-known problem of gathering multiple mobile agents moving in a
graph, but unlike previous results, we consider the problem in the presence of an …

Black hole search with finite automata scattered in a synchronous torus

J Chalopin, S Das, A Labourel, E Markou - Distributed Computing: 25th …, 2011 - Springer
We consider the problem of locating a black hole in synchronous anonymous networks
using finite state agents. A black hole is a harmful node in the network that destroys any …

** pong in dangerous graphs: Optimal black hole search with pebbles

P Flocchini, D Ilcinkas, N Santoro - Algorithmica, 2012 - Springer
We prove that, for the black hole search problem in networks of arbitrary but known topology,
the pebble model of agent interaction is computationally as powerful as the whiteboard …

Black hole search in computer networks: State-of-the-art, challenges and future directions

M Peng, W Shi, JP Corriveau, R Pazzi… - Journal of Parallel and …, 2016 - Elsevier
As the size and use of networks continue to increase, network anomalies and faults are
commonplace. Consequently, effective detection of such network issues is crucial for the …

Map construction and exploration by mobile agents scattered in a dangerous network
