Bidirectional Search for Longest Paths: Case for Front-to-Front Heuristics
Researchers have developed BiXDFBnB, a new bidirectional depth-first branch-and-bound algorithm. This algorithm adapts the Single-Frontier Bidirectional Search framework, originally for shortest paths, to solve the Generalized Longest Simple Path problem. The approach naturally incorporates front-to-front heuristics, aiming to reduce node expansions and potentially improve runtime for longest-path problems like LSP, Snakes, and CIB. AI
