SYNCHRONIZING TO THE ENVIRONMENT: INFORMATION-THEORETIC CONSTRAINTS ON AGENT LEARNING

CRUTCHFIELD, JAMES P.; FELDMAN, DAVID P. - In: Advances in Complex Systems (ACS) 04 (2001) 02, pp. 251-264

Using an information-theoretic framework, we examine how an intelligent agent, given an accurate model of its environment, synchronizes to the environment — i.e., comes to know in which state the environment is. We show that the total uncertainty experienced by the agent during the process is...

MODE-EMERGENCE IN THE SYNCHRONIZED SAILING OF CAMPHOR BOATS

NAKATA, SATOSHI; DOI, YUKIE - In: Advances in Complex Systems (ACS) 06 (2003) 01, pp. 127-135

, various kinds of synchronization could be produced by changing the inherent velocities of the boats. The essential features of … synchronization were reproduced by a numerical calculation regarding the distances among three camphor boats, which changed the …

COOPERATION, COLLECTIVES FORMATION AND SPECIALIZATION

HAUERT, CHRISTOPH - In: Advances in Complex Systems (ACS) 09 (2006) 04, pp. 315-335

Cooperation in spatial evolutionary game theory has revealed various interesting insights into the problem of the evolution and maintenance of cooperative behavior. In social dilemmas, cooperators create and maintain a common resource at some cost to themselves while defectors attempt to exploit...

SYNCHRONIZING TO PERIODICITY: THE TRANSIENT INFORMATION AND SYNCHRONIZATION TIME OF PERIODIC SEQUENCES

FELDMAN, DAVID P.; CRUTCHFIELD, JAMES P. - In: Advances in Complex Systems (ACS) 07 (2004) 03, pp. 329-355

synchronization time τ, which is the average number of measurements required to infer the phase of a periodic signal. We calculate T … transient information is the product of the total phase information and the synchronization time. Despite the latter result, our … analyses demonstrate that the transient information and synchronization time capture different and complementary structural …

CONGESTION AND CENTRALITY IN TRAFFIC FLOW ON COMPLEX NETWORKS

HOLME, PETTER - In: Advances in Complex Systems (ACS) 06 (2003) 02, pp. 163-176

The central points of communication network flow have often been identified using graph theoretical centrality measures. In real networks, the state of traffic density arises from an interplay between the dynamics of the flow and the underlying network structure. In this work we investigate the...

THE NETWORK OF INTER-REGIONAL DIRECT INVESTMENT STOCKS ACROSS EUROPE

BATTISTON, STEFANO; RODRIGUES, JOAO F.; ZEYTINOGLU, HAMZA - In: Advances in Complex Systems (ACS) 10 (2007) 01, pp. 29-51

We present an analysis of inter-regional investment stocks within Europe from a complex networks perspective. We consider two different levels: first, we compute the inward–outward investment stocks at the level of firms, based on ownership shares and number of employees; then we estimate the...

EIGENMODE OF THE DECISION-BY-MAJORITY PROCESS IN COMPLEX NETWORKS

UCHIDA, MAKOTO; SHIRAYAMA, SUSUMU - In: Advances in Complex Systems (ACS) 11 (2008) 04, pp. 565-579

The nature of the dynamics of opinion formation or zero-temperature Ising models modeled as a decision-by-majority process in complex networks is investigated using eigenmode analysis. The Hamiltonian of the system is defined and estimated by eigenvectors of the adjacency matrix constructed from...

IDENTIFYING THE LARGE-SCALE STRUCTURE OF THE BLOGOSPHERE

UCHIDA, MAKOTO; SHIBATA, NAOKI; KAJIKAWA, YUYA; TAKEDA, … - In: Advances in Complex Systems (ACS) 12 (2009) 02, pp. 207-219

We analyze a topological structure of networks formed according to the entries and trackbacks in the blogosphere, which is a collection of weblog articles. The analysis is performed based on community extraction, network visualization and keyword analysis. It is shown that the large-scale...

COMPLEX STRUCTURES AND SEMANTICS IN FREE WORD ASSOCIATION

GRAVINO, PIETRO; SERVEDIO, VITO D. P.; BARRAT, ALAIN; … - In: Advances in Complex Systems (ACS) 15 (2012) 03, pp. 1250054-1

We investigate the directed and weighted complex network of free word associations in which players write a word in response to another word given as input. We analyze in details two large datasets resulting from two very different experiments: On the one hand the massive multiplayer web-based...

TRANSPORTATION NETWORK STABILITY: A CASE STUDY OF CITY TRANSIT

BERCHE, BERTRAND; FERBER, CHRISTIAN VON; HOLOVATCH, TARAS; … - In: Advances in Complex Systems (ACS) 15 (2012) su, pp. 1250063-1

The goals of this paper are to present criteria, that allow to a priori quantify the attack stability of real world correlated networks of finite size and to check how these criteria correspond to analytic results available for infinite uncorrelated networks. As a case study, we consider public...
