Abstract

A Distributed Constraint Optimization Problem (DCOP) is a problem where several agents coordinate with each other to take on values so as to minimize the sum of the resulting constraint costs, which are dependent on the values of the agents. DCOPs are rapidly becoming popular for formulating and solving multi-agent coordination problems such as the distributed coordination of sensors in a network and the distributed scheduling of meetings.

In this talk, I will first describe the formulation for a DCOP and the motivation for using DCOPs in multi-agent coordination problems. I will then provide a brief overview on the leading approaches to solve DCOPs as well as describe some of our recent extensions of the DCOP model and algorithms. Finally, I will wrap up the talk by briefly describing our recent work on applying DCOP algorithms to solve the problem of scheduling smart/IoT devices in smart homes.
