ANALYTICAL AND NUMERICAL INVESTIGATION OF ANT BEHAVIOR UNDER CROWDED CONDITIONS
PETERS, KARSTEN; JOHANSSON, ANDERS; DUSSUTOUR, AUDREY; … - In: Advances in Complex Systems (ACS) 09 (2006) 04, pp. 337-352
Swarm intelligence is widely recognized as a powerful paradigm of self-organized optimization, with numerous examples of successful applications in distributed artificial intelligence. However, the role of physical interactions in the organization of traffic flows in ants under crowded...

HOW INDIVIDUALS LEARN TO TAKE TURNS: EMERGENCE OF ALTERNATING COOPERATION IN A CONGESTION GAME AND THE PRISONER'S DILEMMA
HELBING, DIRK; SCHÖNHOF, MARTIN; STARK, HANS-ULRICH; … - In: Advances in Complex Systems (ACS) 08 (2005) 01, pp. 87-116
In many social dilemmas, individuals tend to generate a situation with low payoffs instead of a system optimum ("tragedy of the commons"). Is the routing of traffic a similar problem? In order to address this question, we present experimental results on humans playing a route choice game in a...

A STUDY ON RESEARCH PERFORMANCE IN JAPANESE UNIVERSITIES: WHICH IS MORE EFFICIENT — A PROFESSOR WHO IS LEADING HIS RESEARCH GROUP OR ONE WHO IS WORKING ALONE? THE MULTI-AGENT SIMUL...
TANIMOTO, JUN; FUJII, HARUYUKI - In: Advances in Complex Systems (ACS) 06 (2003) 03, pp. 375-391
In recent years, we have been interested in the up-and-down prospects of academic societies, including both universities and academies. We have developed a University-Academy Coupling Model, which is built on the multi-agent simulation technique. In the artificial society, there exist both...

FROM SPATIALLY EXPLICIT TO MULTIAGENTS SIMULATION OF URBAN DYNAMIC
SEMBOLONI, FERDINANDO - In: Advances in Complex Systems (ACS) 10 (2007) su, pp. 355-362
In the introduction a distinction is made between the macroscopic approach, which the spatially explicit method is connected with, and the microscopic approach. The spatially explicit method is considered in relation to the interactions between located variables: without and with transport of...

THE SPATIAL AND TEMPORAL DIFFUSION OF STYLISTIC INNOVATIONS IN MATERIAL CULTURE
SCHOLNICK, JONATHAN B. - In: Advances in Complex Systems (ACS) 15 (2012) 01, pp. 1150010-1
Many explanations for the sigmoid or S-shaped curves that characterize the diffusion of innovations through time have … underlying social forces that structure diffusion through both space and time. Using historic New England gravestones and their … among consumers can generate both wave-like diffusion patterns through space and lead to the persistence of cultural …

DYNAMIC BEHAVIOR OF A NONLINEAR SINGLE SPECIES DIFFUSIVE SYSTEM
CHEN, FENGDE; CHEN, XIAOXING; SHI, JINLIN - In: Advances in Complex Systems (ACS) 08 (2005) 04, pp. 399-417
In this paper, we consider the following nonlinear single species diffusive system \begin{eqnarray*} \dot{x}_i(t)&=& x_i(t)\left(b_i(t)-\sum_{k=1}^{l_i}a_{ik}(t)(x_i(t))^{\beta_{ik}}\right)\\ && +\,\sum_{j=1}^{n}D_{ij}(t)(x_j(t)-x_i(t)),\quad (i,j=1,2,\ldots,n), \end{eqnarray*} where bi(t),...

DO LANGUAGE CHANGE RATES DEPEND ON POPULATION SIZE?
WICHMANN, SØREN; STAUFFER, DIETRICH; SCHULZE, CHRISTIAN; … - In: Advances in Complex Systems (ACS) 11 (2008) 03, pp. 357-369
An earlier study [24] concluded, based on computer simulations and some inferences from empirical data, that languages will change the more slowly the larger the population gets. We replicate this study using a more complete language model for simulations (the Schulze model combined with a...
