A general class of combinatorial filters that can be minimized efficiently

Y Zhang, DA Shell - 2023 IEEE International Conference on …, 2023 - ieeexplore.ieee.org
State minimization of combinatorial filters is a fundamental problem that arises, for example,
in building cheap, resource-efficient robots. But exact minimization is known to be NP-hard …

Improper filter reduction

Combinatorial filters have been the subject of increasing interest from the robotics
community in recent years. This paper considers automatic reduction of combinatorial filters …

Nondeterminism subject to output commitment in combinatorial filters

Y Zhang, DA Shell - … Workshop on the Algorithmic Foundations of Robotics, 2022 - Springer
We study a class of filters—discrete finite-state transition systems employed as incremental
stream transducers—that have application to robotics: eg, to model combinatorial estimators …
