      Bounds on FSM switching activity 

      Athanasopoulou, E.; Hadjicostis, Christoforos N. (2008)
      This paper obtains lower and upper bounds for the switching activity on the state lines of a finite state machine (FSM) that is driven by typical input sequences. More specifically, the paper provides bounds on the average ...

      Distributed strategies for average consensus in directed graphs 

      Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (2011)
      We address the average consensus problem for a distributed system whose components (nodes) can exchange information via interconnections (links) that form an arbitrary, strongly connected but possibly directed, topology ...

      Finite-time distributed consensus in graphs with time-invariant topologies 

      Sundaram, S.; Hadjicostis, Christoforos N. (2007)
      We present a method for achieving consensus in distributed systems in a finite number of time-steps. Our scheme involves a linear iteration where, at each time-step, each node updates its value to be a weighted average of ...
