Two new research papers propose novel heuristic approaches for bidirectional search algorithms. The first paper introduces BiXDFBnB, a bidirectional depth-first branch-and-bound algorithm adapted for longest path problems, which aims to reduce node expansions and potentially improve runtime. The second paper presents a new heuristic class called front-to-attractors (F2A), designed to offer the informativeness of front-to-front heuristics with significantly reduced computational overhead by using a smaller set of attractors instead of evaluating all states on the opposite frontier.
