Bidirectional Search for Longest Paths: Case for Front-to-Front Heuristics
Researchers propose BiXDFBnB, a bidirectional depth-first branch-and-bound algorithm that efficiently applies front-to-front heuristics to longest-path problems by adapting the Single-Frontier Bidirectional Search framework. The method reduces computational overhead typically associated with bidirectional frontier management, achieving both fewer node expansions and improved runtime performance on several problem variants.
