Abstract :
[en] This paper addresses the design of algorithms
for the collective optimization of a cost function defined over
average quantities in the presence of limited communication.
We argue that several meaningful collective optimization problems
can be formulated in this way. As an application of
the proposed approach, we propose a novel algorithm that
achieves synchronization or balancing in phase models of
coupled oscillators under mild connectedness assumptions on
the (possibly time-varying and unidirectional) communication
graphs.
