2049 results about "State space" patented technology

In the theory of discrete dynamical systems, a state space is the set of all possible configurations of a system. For example, a system in queueing theory defining the number of customers in a line would have state space {0, 1, 2, 3, ...}. State spaces can be either infinite or finite. An example of a finite state space is that of the toy problem Vacuum World, in which there are a limited set of configurations that the vacuum and dirt can be in.
