Over the past decade there has been growing in interest in distributed optimization and control problems of all types. Among these are consensus and flocking problems, constrained consensus problems, distributed optimization problems, the distributed optimal coverage problem, distributed averaging problems, and distributed formation control problems. The broad aim of these lectures is to explain what these problems are and to discuss their solutions. Related concepts from spectral graph theory, rigid graph theory, nonhomogeneous Markov chain theory, stability theory, optimization theory, and linear system theory will be covered. A. Stephen Morse will discuss "Consensus, Distributed Averaging & Formation Control" Angela Nedich will lecture on "Distributed Optimization over Networks"
