Applying swarm intelligence to a novel congestion control approach for wireless sensor networks
Antoniou, Pavlos Ch.; Pitsillides, Andreas; Engelbrecht, A.; Blackwell, T.; Michael, Loizos (2011)Recently, sensor networks have attracted significant research interest. However, most studies have mainly focused on protocols for applications in which network performance assurances are not considered essential. With the ...

Argumentation: Reconciling human and automated reasoning
Kakas, Antonis C.; Michael, Loizos; Toni, F. (CEUR-WS, 2016)We study how using argumentation as an alternative foundation for logic gives a framework in which we can reconcile human and automated reasoning. We analyse this reconciliation between human and automated reasoning at ...

Ceteris paribus preference elicitation with predictive guarantees
Dimopoulos, Yannis; Michael, Loizos; Athienitou, F. (2009)CP-networks have been proposed as a simple and intuitive graphical tool for representing conditional ceteris paribus preference statements over the values of a set of variables. While the problem of reasoning with CP-networks ...

Computing on a partially eponymous ring
Mavronicolas, Marios; Michael, Loizos; Spirakis, Paul G. (2009)We study the partially eponymous model of distributed computation, which simultaneously generalizes the anonymous and the eponymous models. In this model, processors have identities, which are neither necessarily all ...

Congestion control in wireless sensor networks based on bird flocking behavior
Antoniou, Pavlos Ch.; Pitsillides, Andreas; Blackwell, T.; Engelbrecht, A.; Michael, Loizos (2013)This paper proposes that the flocking behavior of birds can guide the design of a robust, scalable and self-adaptive congestion control protocol in the context of wireless sensor networks (WSNs). The proposed approach ...

Congestion control in wireless sensor networks based on the bird flocking behavior
Antoniou, Pavlos Ch.; Pitsillides, Andreas; Engelbrecht, A.; Blackwell, T.; Michael, Loizos (2009)Recently, performance controlled wireless sensor networks have attracted significant interest with the emergence of mission-critical applications (e.g. health monitoring). Performance control can be carried out by robust ...

Knowledge qualification through argumentation
Michael, Loizos; Kakas, Antonis C. (2009)We propose a framework that brings together two major forms of default reasoning in Artificial Intelligence: default property classification in static domains, and default property persistence in temporal domains. Emphasis ...

Modular-E and the role of elaboration tolerance in solving the qualification problem
Kakas, Antonis C.; Michael, Loizos; Miller, R. (2010)We describe Modular-E (ME), a specialized, model-theoretic logic for reasoning about actions. ME is able to represent non-deterministic domains involving concurrency, static laws (constraints), indirect effects (ramifications), ...

Modular-ε: An elaboration tolerant approach to the ramification and qualification problems
Kakas, Antonis C.; Michael, Loizos; Miller, R. (2005)We describe Modular-ε (Mε), a specialized, modeltheoretic logic for narrative reasoning about actions, able to represent non-deterministic domains involving concurrency, static laws (constraints) and indirect effects ...

The price of defense
Mavronicolas, Marios; Michael, Loizos; Lesta, Vicky Papadopoulou; Philippou, Anna; Spirakis, Paul G. (2006)We consider a strategic game with two classes of confronting randomized players on a graph G(V, E): v attackers, each choosing vertices and wishing to minimize the probability of being caught, and a defender, who chooses ...

Programming cognitive
Michael, Loizos; Kakas, Antonis C.; Miller, R.; Turán, G. (CEUR-WS, 2015)The widespread access to computing-enabled devices and the World Wide Web has, in a sense, liberated the ordinary user from reliance on technically-savvy experts. To complete this emancipation, a new way of interacting ...

A psychology-inspired approach to automated narrative text comprehension
Diakidoy, Irene-Anna N.; Kakas, Antonis C.; Michael, Loizos; Miller, R. (AAAI press, 2014)We report on an ongoing research program to develop a formal framework for automated narrative text comprehension, bringing together know-how from research in Artificial Intelligence and the Psychology of Reading and ...

Reasoning about actions and change in answer set programming
Dimopoulos, Yannis; Kakas, Antonis C.; Michael, Loizos (Springer Verlag, 2004)This paper studies computational issues related to the problem of reasoning about actions and change (RAC) by exploiting its link with the Answer Set Programming paradigm. It investigates how increasing the expressiveness ...

STAR: A system of argumentation for story comprehension and beyond
Diakidoy, Irene-Anna N.; Kakas, Antonis C.; Michael, Loizos; Miller, R. (AI Access Foundation, 2015)This paper presents the STAR system, a system for automated narrative comprehension, developed on top of an argumentation-theoretic formulation of defeasible reasoning, and strongly following guidelines from the psychology ...

Story Comprehension through Argumentation
Diakidoy, Irene-Anna N.; Kakas, Antonis C.; Michael, Loizos; Miller, R. (2014)This paper presents a novel application of argumentation for automated Story Comprehension (SC). It uses argumentation to develop a computational approach for SC as this is understood and studied in psychology. Argumentation ...

A substitution theorem for graceful trees and its applications
Mavronicolas, Marios; Michael, Loizos (2009)A graceful labeling of a graph G = (V, E) assigns | V | distinct integers from the set {0, ..., | E |} to the vertices of G so that the absolute values of their differences on the | E | edges of G constitute the set {1, ...
