You discovered: MINIMAX LOCATION!
You did not only help the nearest cove. You kept moving beacons until the single farthest cove had the shortest possible journey.
That is worst-case optimization, also called the k-center problem: choose a limited number of centers, connect every place to its nearest center, then minimize the longest connection. Cities use it to place fire stations, hospitals, Wi-Fi towers, and rescue bases so nobody is dangerously far from help.
Next quest: another advanced thinking adventure awaits.
