In recent years there has been a surge of interest on behalf of the algorithmic community in applying its theoretical tools to the understanding of complex systems, in particular biological ones, such as insect colonies, flocks of birds, and networks of neurons. We contribute to the investigation of such systems in three different directions. First, we analyze computational dynamics for stochastic coordination tasks in multi-agent systems: in particular, we focus on the consensus problem in environments where communication is affected by some form of noise. In this setting, we analyze two known opinion dynamics, the Undecided-State and the 3-Majority dynamics, and prove that they exhibit a phase-transition at different noise thresholds. Bel...
