    Zhang, Hai-Tao ; Chen, Michael ZhiQiang ; Zhou, Tao ; Stan, Guy-Bart

    In: EPL Europhysics Letters, 2008, vol. 83, no. 4, p. 40003

    An important natural phenomenon surfaces that ultrafast consensus can be achieved by introducing predictive mechanisms. By predicting the dynamics of a network several steps ahead and using this information in the consensus protocol, it is shown that, without changing the topology of the network, drastic improvements can be achieved in terms of the speed of convergence towards consensus and of...

    Collective behavior coordination with predictive mechanisms

    Zhang, Hai-Tao ; Chen, Michael ZhiQiang ; Stan, Guy-Bart ; Zhou, Tao ; Maciejowski, Jan M.

    In: IEEE Circuits and Systems Magazine, 2008, vol. 6, no. 3, p. 67 - 85

    In natural flocks/swarms, it is very appealing that low-level individual intelligence and communication can yield advanced coordinated collective behaviors such as congregation, synchronization and migration. In the past few years, the discovery of collective flocking behaviors has stimulated much interest in the study of the underlying organizing principles of abundant natural groups, which has...
