In real world situations, each person is generally in contact with only a small fraction of the entire population and exchange information through these interactions. Their number and their frequency vary from one to another individual and may be much depending on mobility of individuals. The objective of this article is to better understand...

In this paper, we focus on the very specificity of rumors as pieces of information for modeling their process of propagation. We consider a population of pedestrians walking in a city and we assume that a rumor is transmitted by word of mouth from one to another. Although the diffusion of a rumor is of course a multi-dimensional process driven...

The study of information dissemination in social networks is of particular importance in many areas as marketing, politics and security for example. Various strategies are being developed to disseminate information, those aimed at disseminating information widely and those aimed at disseminating information in a more confidential manner to make...

The central subject of this paper is the relation between the macro-level of the Society and the micro-level of its individuals. In complex real-life systems, this relationship is not trivial and even the result at the macro-level can be counter-intuitive. One of the first models that highlights this is the Sakoda and Schelling's model of...

This paper proposes to model a world populated by learners where each one has his own behaviour which is expressed by his way to follow a school curricula. The paper deals with peer learning and, especially, with the school exclusion phenomena. The aim is to answer the question: even if we make the assumption that all the learners are...

From the Schelling model of segregation, we derive models of group formation that shed light on segregation or mixing patterns observed in spatial grid networks. Individuals have types and see type-dependent benefits or drawback from theirs neighbours: this leads each one to be attracted or repulsed by its own like or unlike. This framework...

This paper deals with peer learning and, in particular, with the phenomena of exclusion; it proposes to model a group of learners where everyone has his own behaviour that expresses his way of following a curriculum.The focus is on individual motivations that avoid disadvantage certain individuals while optimising behaviour at the community...

Abstract This article deals with individuals moving in procession in real and artificial societies. A procession is a minimal form of society in which individual behavior is to go in a given direction and the organization is structured by the knowledge of the one ahead. This simple form of grouping is common in the living world, and, among...

In the framework of Agent-Based Complex Systems we examine dynamics that lead individuals towards spatial segregation. Such systems are constituted of numerous entities, among which local interactions create global patterns which cannot be easily related to the properties of the constituent entities. In the 70's, Thomas C. Schelling showed that...

The general context of this paper is the Bass model which presented a theory of the adoption of new products. We propose an agent based modelling to allow to model the respective grow of competing products. We assume that there is competition for the same market among two trademarks: each one has its own rate of spontaneous innovation and its...

This paper presents a neurogenesis process based on the protein regulation system. The novelty consists in applying some genetic algorithm work with neurogenesis, in particular work on genetic operators and work on fitness landscapes. In order to get relevant tests with reduced simulation costs, neurogenesis is applied to a well know problem,...

Genetic algorithms are known to be convergent algorithms, with final population tending to become homogeneous. In this paper we show that it is possible to exhibit complex dynamics for a genetic algorithm by slightly modifying the canonical algorithm. Indeed, adding a meta level in the interpretation of the individuals, associated with a...

This paper deals with the way dual genetic algorithms (dga), an extension of the standard ones, explore the search space. After a brief introduction presenting genetic algorithms and dualism, the fitness distance correlation is discussed in the context of dualism. From this discussion, a conjecture is made about the genetic heuristic used by...
