Method Detail

update

BeliefState update(BeliefState belief,
                   State observation,
                   Action a)

Computes a new belief distribution from a previous belief and given a new observation received after taking a specific action.

Parameters:

belief - the prior belief

observation - the conditioned POMDP observation defined by a State instance.

a - the conditioned action selection in the previous time step.

Returns:

the new belief state distribution represented by a new BeliefState instance.
