Bidirectional Search That Is Guaranteed to Meet in the Middle: Extended Version
We present MM, the first bidirectional heuristic search algorithm whose forward and backward searches are guaranteed to “meet in the middle”, i.e. never expand a node beyond the solution midpoint. We also present a novel framework for comparing MM, A*, and brute-force search, and identify conditions favoring each algorithm. Finally, we present experimental results that support our theoretical a...

متن کاملThe Minimal Set of States that Must Be Expanded in a Front-to-End Bidirectional Search
A* is optimal among admissible unidirectional algorithms when searching with a consistent heuristic. Recently, similar optimality bounds have been established for bidirectional search but, no practical algorithm is guaranteed to always achieve this bound. In this paper we study the nature of the number of nodes that must be expanded in any front-to-end bidirectional search. We present an effici...
متن کاملComparing the Bidirectional Baum-Welch Algorithm and the Baum-Welch Algorithm on Regular Lattice
A profile hidden Markov model (PHMM) is widely used in assigning protein sequences to protein families. In this model, the hidden states only depend on the previous hidden state and observations are independent given hidden states. In other words, in the PHMM, only the information of the left side of a hidden state is considered. However, it makes sense that considering the information of the b...
متن کاملD-Node Retargeting in Bidirectional Heuristic Search
AIthough it is generally agreed that bidirectional heuristic search is potentially more efficient than unidirectional heuristic search, so far there have been no algorithms which realize this potential. The basic difficulty is that the two search trees (one rooted at the start, the other at the goal) do not meet in the middle. This results in essentiofly two unidirectional starches and poorer p...
