[HTML][HTML] Gathering robots in graphs: The central role of synchronicity

S Cicerone, G Di Stefano, A Navarra - Theoretical Computer Science, 2021 - Elsevier
The Gathering task for k robots disposed on the n vertices of a graph G requires robots to
move toward a common vertex from where they do not move anymore. When dealing with …

“semi-asynchronous”: a new scheduler in distributed computing

S Cicerone, G Di Stefano, A Navarra - IEEE Access, 2021 - ieeexplore.ieee.org
The study of mobile entities that based on local information have to accomplish global tasks
is of main interest for the scientific community. Classic models for the activation and …

the Point Convergence problem: given an arbitrary initial configuration of entities, disposed …

Asynchronous robots on graphs: Gathering

S Cicerone, G Di Stefano, A Navarra - Distributed Computing by Mobile …, 2019 - Springer
Gathering a swarm of robots is one of the basic tasks in distributed computing. Varying of the
robots' capabilities as well as on the environments where robots move lead to very different …

Gathering

P Flocchini - Distributed Computing by Mobile Entities: Current …, 2019 - Springer
In this Chapter, we focus on the Gathering problem: that is, the problem of having the robots,
initially located in arbitrary distinct points of the plane, gather in the exact same location. In …

Time optimal gathering of myopic robots on an infinite triangular grid

P Goswami, A Sharma, S Ghosh, B Sau - Theoretical Computer Science, 2025 - Elsevier
