A Fast Bi-Directional A* Algorithm Based on Quad-Tree Decomposition and Hierarchical Map
IEEE Access, 2021 Although the popular path-planning algorithms based on graph-search such as Dijkstra and A* guarantee to find the optimal path, the search time will increase rapidly with the growth of map size.

Hierarchical D ∗ algorithm with materialization of costs for robot path planning [PDF]
, 2005 In this paper a new hierarchical extension of the D ∗ algorithm for robot path planning is introduced. The hierarchical D ∗ algorithm uses a down-top strategy and a set of precalculated paths (materialization of path costs) in order to improve ...

Improved DOA estimation using polarisation diversity : simulations using a wideband propagation model [PDF]
, 2000 This paper investigates the performance of a number of direction-of-arrival (DOA) estimation algorithms in a wideband macrocellular channel using a dual-polarised antenna array.

Learning to Plan Hierarchically From Curriculum [PDF]
IEEE Robotics and Automation Letters, 2019 We present a framework for learning to plan hierarchically in domains with unknown dynamics. We enhance planning performance by exploiting problem structure in several ways: (i) We simplify the search over plans by leveraging knowledge of skill objectives, (ii) Shorter plans are generated by enforcing aggressively hierarchical planning, (iii) We learn ...

This Is a Solution! (... But Is It Though?) - Verifying Solutions of Hierarchical Planning Problems
International Conference on Automated Planning and Scheduling, 2017 Plan-Verification is the task of determining whether a plan is a solution to a given planning problem. Any plan verifier has, apart from showing that verifying plans is possible in practice, a wide range of possible applications.

Incorporating Domain-Independent Planning Heuristics in Hierarchical Planning
AAAI Conference on Artificial Intelligence, 2017 Heuristics serve as a powerful tool in modern domain-independent planning (DIP) systems by providing critical guidance during the search for high-quality solutions. However, they have not been broadly used with hierarchical planning techniques, which

FEBS Open Bio, EarlyView.KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

On Removing Left Recursion from Totally-ordered HTN Domain Models
Proceedings of the International Florida Artificial Intelligence Research Society ConferenceHierarchical planning is a knowledge-based approach to automated planning, where high-level (compound) tasks are decomposed into simpler tasks until primitive tasks – actions – forming the plan are obtained.
