Geometric Aspects of Multiagent Systems
Recent advances in Multiagent Systems (MAS) and Epistemic Logic within
Distributed Systems Theory, have used various combinatorial structures that
model both the geometry of the systems and the Kripke model structure of models
for the logic. Examining one of the simpler versions of these models,
interpreted systems, and the related Kripke semantics of the logic (an
epistemic logic with -agents), the similarities with the geometric /
homotopy theoretic structure of groupoid atlases is striking. These latter
objects arise in problems within algebraic K-theory, an area of algebra linked
to the study of decomposition and normal form theorems in linear algebra. They
have a natural well structured notion of path and constructions of path
objects, etc., that yield a rich homotopy theory.Comment: 14 pages, 1 eps figure, prepared for GETCO200
A conceptual framework for interactive virtual storytelling
This paper presents a framework of an interactive storytelling system. It can integrate five components: management centre, evaluation centre, intelligent virtual agent, intelligent virtual environment, and users, making possible interactive solutions where the communication among these components is conducted in a rational and intelligent way. Environment plays an important role in providing heuristic information for agents through communicating with the management centre. The main idea is based on the principle of heuristic guiding of the behaviour of intelligent agents for guaranteeing the unexpectedness and consistent themes
Analyzing controllability of neural networks
In recent years, due to the relation between cognitive control and mathematical concept of control dynamical systems, there has been growing interest in the descriptive analysis of complex networks with linear dynamics, permeating many aspects from everyday life, obtaining considerable advances in the description of their structural
and dynamical properties. Nevertheless, much less effort has been devoted to studying the controllability of the dynamics taking place on them. Concretely, for complex systems is of interest to study the exact controllability, this measure is defined as the minimum set of controls that are needed to steer the whole system toward any desired
state. In this paper, a revision of controllability concepts is presented and provides conditions for exact controllability for the multiagent systemsPostprint (author's final draft
Context-dependent Trust Decisions with Subjective Logic
A decision procedure implemented over a computational trust mechanism aims to
allow for decisions to be made regarding whether some entity or information
should be trusted. As recognised in the literature, trust is contextual, and we
describe how such a context often translates into a confidence level which
should be used to modify an underlying trust value. J{\o}sang's Subjective
Logic has long been used in the trust domain, and we show that its operators
are insufficient to address this problem. We therefore provide a
decision-making approach about trust which also considers the notion of
confidence (based on context) through the introduction of a new operator. In
particular, we introduce general requirements that must be respected when
combining trustworthiness and confidence degree, and demonstrate the soundness
of our new operator with respect to these properties.Comment: 19 pages, 4 figures, technical report of the University of Aberdeen

The Total s-Energy of a Multiagent System
We introduce the "total s-energy" of a multiagent system with time-dependent
links. This provides a new analytical lens on bidirectional agreement dynamics,
which we use to bound the convergence rates of dynamical systems for
synchronization, flocking, opinion dynamics, and social epistemology
