    • Cartesian product partitioning of multi-dimensional reachable state spaces 

      Dayar T.; Orhan, M. C. (Cambridge University Press, 2016)
      Markov chains (MCs) are widely used to model systems which evolve by visiting the states in their state spaces following the available transitions. When such systems are composed of interacting subsystems, they can be ...
