Abstract
Filtering denotes any method whereby an agent up­
dates its belief state---its knowledge of the state of
the world---from a sequence of actions and obser­
vations. In logical filtering, the belief state is a log­
ical formula describing possible world states and
the agent has a (possibly nondeterministic) logi­
cal model of its environment and sensors. This
paper presents efficient logical filtering algorithms
that maintain a compact belief state representa­
tion indefinitely, for a broad range of environment
classes including nondeterministic, partially ob­
servable STRIPS environments and environments
in which actions permute the state space. Efficient
