Chaotic Evolutionary Algorithms for Multi-Reservoir Optimization
Arunkumar, R.; Jothiprakash, V. - In: Water Resources Management 27 (2013) 15, pp. 5207-5222
The water sharing dispute in a multi-reservoir river basin forces the water resources planners to have an integrated operation of multi-reservoir system rather than considering them as a single reservoir system. Thus, optimizing the operations of a multi-reservoir system for an integrated...

Investigating Chaos in Tehran Stock Exchange Index
Moeini, Ali; Ahrari, Mehdi; Madarshahi3, Saeed Sadat - In: Iranian Economic Review 12 (2007) 1, pp. 103-120
Modeling and analysis of future prices has been hot topic for economic analysts in recent years. Traditionally, the complex movements in the prices are usually taken as random or stochastic process. However, they may be produced by a deterministic nonlinear process. Accuracy and efficiency of...

Simple and Complex Dynamics: A Hidden Parameter
Medio, Alfredo - Groupe de REcherche en Droit, Économie, Gestion … - 2013
In discrete-time dynamical systems arising from economic problems, the length of the period (henceforth simply "period") separating two successive values of the state variables may play an essential role in determining the type of dynamics followed by the system. In economics, this fact is...

Modeling intrinsic noise in random Boolean networks
Hung, Yao-Chen; Lin, Chai-Yu - In: Physica A: Statistical Mechanics and its Applications 395 (2014) C, pp. 121-127
Noise has crucial effects on biological processes, chemical reactions, and various chaotic systems. This study explores the dynamical properties of noise in random Boolean networks, in which the stochasticity may cause significant deviations from deterministic descriptions. Such noise is...

Adaptive–impulsive synchronization of chaotic systems
Wan, Xiaojun; Sun, Jitao - In: Mathematics and Computers in Simulation (MATCOM) 81 (2011) 8, pp. 1609-1617
In this paper, we investigate nonlinear adaptive–impulsive synchronization of chaotic systems. The core of adaptive–impulsive synchronization of chaotic systems is to design suitable nonlinear adaptive–impulsive controllers to attain certain aims. Based on invariant principle of impulsive...
