Convergence to Equilibrium in Local Interaction Games
Game theory model the network the dynamic modeling
2015/8/21
We study a simple game-theoretic model for the spread of an innovation in a network. The diffusion of the innovation is modeled as the dynamics of a coordination game in which the adoption of a common...
Fast Convergence of Natural Bargaining Dynamics in Exchange Networks
Network model games a distributed algorithm
2015/8/21
Bargaining networks model the behavior of a set of players that need to reach pairwise agree-ments for making profits. Nash bargaining solutions are special outcomes of such games that are both stable...
On parameter convergence in adaptive control
Control parameter the parameter error signal and reference signal
2015/8/13
It is well known that the parameter error as well as the model-plant mismatch error in a model reference adaptive scheme tends exponentially to zero iff a certain sufficient richness condition holds f...
