To find these crucial border points, we employed a clever technique based on the Ford-Fulkerson algorithm. By simulating "flooding" roads with traffic from random start/end points, we could identify the natural bottlenecks – the "minimum cut" in graph theory terms. These bottlenecks became our border points.
The last fully unique phase is phase 1, which basically undoes the work of phase 7. However, phases 2-5 will also need to turn the phase number into a index ranging from 0-3, so instead of comparing the value against 1 we decrement it and check if that made it zero:
