Cost of synchronizing different chaotic systems

Sarasola, C.; Torrealdea, F.J.; d’Anjou, A.; Graña, M. - In: Mathematics and Computers in Simulation (MATCOM) 58 (2002) 4, pp. 309-327

Feedback coupling provides a general scheme for synchronizing two oscillatory chaotic systems through the intervention of a term of interaction that accounts for the difference of behaviors. We define a cost of synchronization based on a measure of the interaction term. Synchronizing different...

A collective motion algorithm for tracking time-dependent boundaries

Triandaf, Ioana; Schwartz, Ira B. - In: Mathematics and Computers in Simulation (MATCOM) 70 (2005) 4, pp. 187-202

We present a numerical method that allows a formation of communicating agents to target the boundary of a time-dependent concentration by following a time-dependent concentration gradient. The algorithm motivated by [3,1], allows the agents to move in space in a non-stationary environment. Our...
