An introduction to temporal graphs: An algorithmic perspective

O Michail - Internet Mathematics, 2016 - Taylor & Francis
A temporal graph is, informally speaking, a graph that changes with time. When time is
discrete and only the relationships between the participating entities may change and not …

[HTML][HTML] Traveling salesman problems in temporal graphs

O Michail, PG Spirakis - Theoretical Computer Science, 2016 - Elsevier
In this work, we introduce the notion of time to some well-known combinatorial optimization
problems. In particular, we study problems defined on temporal graphs. A temporal graph …

Temporal network optimization subject to connectivity constraints

GB Mertzios, O Michail, PG Spirakis - Algorithmica, 2019 - Springer
In this work we consider temporal networks, ie networks defined by a labeling λ λ assigning
to each edge of an underlying graph G a set of discrete time-labels. The labels of an edge …

Mediated population protocols

O Michail, I Chatzigiannakis, PG Spirakis - Theoretical Computer Science, 2011 - Elsevier
We extend here the Population Protocol (PP) model of Angluin et al.(2004, 2006)[2, 4] in
order to model more powerful networks of resource-limited agents that are possibly mobile …

Simple and efficient local codes for distributed stable network construction

O Michail, PG Spirakis - Proceedings of the 2014 ACM symposium on …, 2014 - dl.acm.org
In this work, we study protocols so that populations of distributed processes can construct
networks. In order to highlight the basic principles of distributed network construction we …

Passively mobile communicating machines that use restricted space

I Chatzigiannakis, O Michail, S Nikolaou… - Proceedings of the 7th …, 2011 - dl.acm.org
We propose a new theoretical model for passively mobile Wireless Sensor Networks, called
PM, standing for Passively mobile Machines. The main modification wrt the Population …

Shortest, fastest, and foremost broadcast in dynamic networks

A Casteigts, P Flocchini, B Mans… - International Journal of …, 2015 - World Scientific
Highly dynamic networks rarely offer end-to-end connectivity at a given time. Yet,
connectivity in these networks can be established over time and space, based on temporal …
