SECURITY AS IMMUNITY IN VIRTUAL ORGANIZATIONS (2009)

Elpida S. Tzafestas

We are addressing the class of virtual organizations where an entrepreneurial or other activity acts as an interface between a number of existing remote services or applications and a number of...

Why age? (2008)

Elpida S. Tzafestas

Abstract We are adopting Brooks and Wiley's view of evo-lution as an irreversible process capable of producing in-creasingly greater complexity at higher organizational levels. We start from the...

MONDRIANULOR: Exploring the interaction between harmonic division and coloring (2008)

Elpida S. Tzafestas, Harmonic Colorings, Le Corbusier

We are proposing MOnDrianULOR, a system capable of producing visual forms based on the works of Swiss architect Le Corbusier and Dutch artist Piet Mondrian. The system produces visual forms that...

REGULATION PROBLEMS IN EXPLORER AGENTS (2008)

Elpida S. Tzafestas

In the present study, we investigate and analyze the behavior of explorer agents. We perform a number of experiments with single and multiple agents and we obtain a number of corresponding results....

REACTIVE ROBOTS IN THE SERVICE OF PRODUCTION MANAGEMENT (2007)

Elpida S. Tzafestas

In this paper, we advocate the use of reactive robots in industrial process control and production management. It is explained why reactive robots are well-suited to modern industrial applications...

A Study on Self-Organization in a Production Environment (2007)

Elpida S. Tzafestas

Modern cellular manufacturing systems involve distributed environments of robots, machines, materials etc. The principal feature of such a system is that incomplete or imperfect information is given...

Ofautonomous (2007)

Robots Elpida, Elpida S. Tzafestas

. This paper describes work on design principles for autonomous robots societies. The design problem is formulated as a decision problem where an optimisation formula is applied to a set of design...

Integrating Drawing Tools with Behavioral Modeling (2000)

Elpida S. Tzafestas

Our goal is to integrate traditional artistic media that demand hand dexterity (such as drawing) with intelligent systems techniques that may both constrain and nourish this dexterity. To this end we...

Toward adaptive cooperative behavior (2000)

Elpida S. Tzafestas

We analyze the Iterated Prisoner’s Dilemma and the performance of GRADUAL, the best behavior found so far. This behavior has the undesirable property of permanent memory, which would be detrimental...

Spatial games with adaptive tit-for-tats (2000)

Elpida S. Tzafestas

Abstract. This paper presents an adaptive tit-for-tat strategy and a study of its behavior in spatial IPD games. The adaptive tit-for-tat strategy is shown elsewhere to demonstrate high performance...

Experiences from the Development and Use of Simulation Software for Complex Systems (2000)

Elpida S. Tzafestas

Abstract. In this paper, we present our lessons from the design and use of two educational software tools for teaching behavioral modeling to graduate students of digital art. The tools, PainterAnts...

Series as an Expression Model (2000)

Elpida S. Tzafestas

This work is situated within the scope of the emerging complexity sciences and tries to bridge scientific and artistic intentions for understanding complexity by doing experiments. To this end, we...

A Cellular Control Architecture for Autonomous Robots (1994)

Elpida S. Tzafestas

This paper presents a cellular control architecture for autonomous robots. This architecture, which is an instanciation of the behaviour-based paradigm, i) defines the cell as the elementary unit of...

Operational coupling: A design principle and an intermediate representation level (1994)

Elpida S. Tzafestas

. This paper investigates the hypothesis that the motivational system of an autonomous agent should be operationally coupled with the world it is situated in. Operational coupling is structural...

Agentifying the Process: Task-Based or Robot-Based Decomposition (1994)

Elpida S. Tzafestas

In this paper we advocate the use of multi-agent systems in cellular manufacturing. More specifically, we argue that multi-agent systems can respond to the flexibility and adaptivity needs of modern...

A Design Framework for Societies of Autonomous Robots (1994)

Elpida S. Tzafestas

This paper describes work on design principles for autonomous robots societies. The design problem is formulated as a decision problem where an optimisation formula is applied to a set of design...
