“…Early references of this approach in the context of distributed optimization are [14], [15]. More recent works exploiting singular perturbations are [16]- [20] in the context of distributed optimization and [21]- [23] in the one of games. In order to deal with agreement on global information in our schemes, we resort to the formalism of ς-consensus [24], [25], modeling problems in which a set of agents, each endowed with a local quantity s t i and a common generic function ς, aims to reach consensus at ς(s t 1 , .…”
