- Imply-field Video games for Bio-inspired Collective Resolution-making in Dynamical Networks(arXiv)
Summary : Given numerous homogeneous gamers which are distributed throughout three potential states, we think about the issue by which these gamers have to manage their transition charges, whereas minimizing a price. The optimum transition charges are primarily based on the gamers’ information of their present state and of the distribution of all the opposite gamers, and this introduces mean-field phrases within the working and the terminal price. The primary contribution includes a mean-field sport mannequin that brings collectively macroscopic and microscopic dynamics. We get hold of the mean-field equilibrium related to this mannequin, by fixing the corresponding initial-terminal worth drawback. We carry out an asymptotic evaluation to acquire a stationary equilibrium for the system. The second contribution includes the examine of the microscopic dynamics of the system for a finite variety of gamers that work together in a structured atmosphere modeled by an interplay topology. The third contribution is the specialization of the mannequin to explain honeybee swarms, virus propagation, and cascading failures in interconnected smart-grids. A numerical evaluation is performed which includes two sorts of cyber-attacks. We simulate by which methods failures propagate throughout the interconnected sensible grids and the impression on the grids frequencies. We reframe our evaluation throughout the context of Lyapunov’s linearisation methodology and stability principle of nonlinear programs and Kuramoto coupled oscillators mannequin.
2. Multiequilibria evaluation for a category of collective decision-making networked programs(arXiv)
Summary : The fashions of collective decision-making thought of on this paper are nonlinear interconnected cooperative programs with saturating interactions. These programs encode the potential outcomes of a choice course of into completely different regular states of the dynamics. Specifically, they’re characterised by two important attractors within the constructive and adverse orthant, representing two selections of settlement among the many brokers, related to the Perron-Frobenius eigenvector of the system. On this paper we give circumstances for the looks of different equilibria of combined signal. The circumstances are impressed by Perron-Frobenius principle and are associated to the algebraic connectivity of the community. We additionally present how all these equilibria have to be contained in a stable disk of radius given by the norm of the equilibrium level which is situated within the constructive orthant
