IDENTIFYING NEURAL NETWORK TOPOLOGIES THAT FOSTER DYNAMICAL COMPLEXITY

YAEGER, LARRY S. - In: Advances in Complex Systems (ACS) 16 (2013) 02, pp. 1350032-1

between an information theoretic measure of the complexity of neural dynamics and several graph theoretical metrics calculated … evolutionary selection for complexity and small-world network properties during periods of behavioral adaptation. The resultant … between network structure and function. The highest complexity networks are found within limited numerical ranges of …

COMPLEXITY OF AN IVLEV'S PREDATOR-PREY MODEL WITH PULSE

PANG, GUOPING; CHEN, LANSUN - In: Advances in Complex Systems (ACS) 10 (2007) 02, pp. 217-231

In this paper, we investigate the extinction, permanence and dynamic complexity of the two-prey, one-predator system … many forms of complexity including period-doubling bifurcation, period-halving bifurcation, and chaos. …

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

We analyze how difficult it is to synchronize to a periodic sequence whose structure is known, when an observer is initially unaware of the sequence's phase. We examine the transient information T, a recently introduced information-theoretic quantity that measures the uncertainty an observer...

CHAOTIC BEHAVIOR OF A PERIODICALLY FORCED PREDATOR–PREY SYSTEM WITH BEDDINGTON–DEANGELIS FUNCTIONAL RESPONSE AND IMPULSIVE PERTURBATIONS

ZHANG, SHUWEN; TAN, DEJUN; CHEN, LANSUN - In: Advances in Complex Systems (ACS) 09 (2006) 03, pp. 209-222

The effects of periodic forcing and impulsive perturbations on the predator–prey model with Beddington–DeAngelis functional response are investigated. We assume periodic variation in the intrinsic growth rate of the prey as well as periodic constant impulsive immigration of the predator. The...

COMPLEXITY: METRICS AND MODULES

BOSSOMAIER, TERRY - In: Advances in Complex Systems (ACS) 06 (2003) 03, pp. 313-329

measurement of system complexity is still imprecise. For many systems, their modular construction brings challenges in … communication protocols which allow complexity to increase dramatically. We take a broad view of these issues and then consider the … nature of the system space which generates complexity. We show examples from cellular automata and applications of neural …

ECONOPHYSICS AND ECONOMIC COMPLEXITY

ROSSER, J. BARKLEY - In: Advances in Complex Systems (ACS) 11 (2008) 05, pp. 745-760

complexity, and how this relates to issues in econophysics. It then reviews the criticisms that have been raised about ways in … to work with economists who understand the complexity critique of conventional economic theory and are thus not led …

SUM RULE FOR MULTISCALE REPRESENTATIONS OF KINEMATICALLY DESCRIBED SYSTEMS

BAR-YAM, YANEER - In: Advances in Complex Systems (ACS) 05 (2002) 04, pp. 409-431

We derive a sum rule that constrains the scale based decomposition of the trajectories of finite systems of particles. The sum rule reflects a tradeoff between the finer and larger scale collective degrees of freedom. For short duration trajectories, where acceleration is irrelevant, the sum...

A SIMULATION OF THE IMPACT OF MEDIA ON SOCIAL COHESION

STOCKER, ROB; CORNFORTH, DAVID; GREEN, DAVID G. - In: Advances in Complex Systems (ACS) 06 (2003) 03, pp. 349-359

One impact of the introduction of television, according to widely held views, is an undermining of traditional values and social organization. In this study, we simulate this process by representing social communication as a Random Boolean Network in which the individuals are nodes, and each...

DYNAMIC COMPLEXITIES OF A CHEMOSTAT MODEL WITH PULSED INPUT AND WASHOUT AT DIFFERENT TIMES

ZHANG, SHUWEN; TAN, DEJUN; GU, HONGSHENG - In: Advances in Complex Systems (ACS) 11 (2008) 01, pp. 65-76

In this paper, we consider a predator–prey chemostat model with ratio-dependent Monod type functional response and periodic input and washout at different fixed times. We obtain an exact periodic solution with substrate and prey. The stability analysis for this periodic solutions yields an...

MULTISCALE COMPLEXITY/ENTROPY

BAR-YAM, Y. - In: Advances in Complex Systems (ACS) 07 (2004) 01, pp. 47-63

We discuss the role of scale dependence of entropy/complexity and its relationship to component interdependence. The … complexity as a function of scale of observation is expressed in terms of subsystem entropies for a system having a description … in terms of variables that have the same a priori scale. The sum of the complexity over all scales is the same for any …
