Greedy path finding
WebSep 28, 2024 · We update the distances of these nodes to the source node, always trying to find a shorter path, if possible: For node 4: the distance is 17 from the path 0 -> 1 -> 3 -> 4. For node 5: the distance is 22 from the path 0 -> 1 -> 3 -> 5. 💡 Tip: Notice that we can only consider extending the shortest path (marked in red). WebDec 15, 2024 · Greedy Best-First Search is an AI search algorithm that attempts to find the most promising path from a given starting point to a goal. It prioritizes paths that appear …
