Researchers have developed a new branch and bound algorithm to solve the logic-constrained shortest path problem, which is applicable to flight planning with air traffic control restrictions. The algorithm offers flexibility through choices in node selection, branching rules, and conflict handling. An empirical analysis demonstrated that optimizing these choices can improve performance by an order of magnitude, and the approach was tested on a global flight graph with real-world traffic flow restrictions from Lufthansa Systems.
