All Superinterfaces:

BeliefState, State

All Known Subinterfaces:

DenseBeliefVector

All Known Implementing Classes:

TabularBeliefState

public interface EnumerableBeliefState
extends BeliefState

An interface to be used by BeliefState implementations that also can enumerate the set of states that have probability mass. The probability mass of a state is specified by the EnumerableBeliefState.StateBelief class which is a pair consisting of an MDP state defined by a State instance, and its probability mass, defined by a double.

Method Detail

nonZeroBeliefs

java.util.List<EnumerableBeliefState.StateBelief> nonZeroBeliefs()

Returns the states, and their probability mass, that have non-zero probability mass. States that are not included in the returned listed are assumed to have probability mass zero.

Returns:

a List of EnumerableBeliefState.StateBelief objects specifying the enumerated probability mass function.
