This "wall-following" or "path-sensing" algorithm works even if the obstacles shift slightly, which is a key requirement for higher scores in this level. Code Length: rapid router level 48 solution verified

Performance and scalability considerations

• For |V| = 48, exact MILP may be feasible for batch computations; runtime targets (sub-second updates) require heuristics, incremental solving, and parallelization.
• Clustering reduces solver state; caching and delta updates accelerate repeated computations.
• Precomputing alternate paths and using fast reroute mechanisms provide sub-second failover, while full recomputation can run asynchronously.
