WebOct 17, 2024 · Dijkstra’s algorithm, part 5. When we sum the distance of node d and the cost to get from node d to e, we’ll see that we end up with a value of 9, which is less than 10, the current shortest ... WebNov 9, 2015 · Not quite. If D [v] + G [v] [w] == G [w], that doesn't mean you've found one provisionally-shortest path to w. After all, there might be multiple shortest paths to v, and each one gives you a provisionally-shortest path to w. You need to add v's counter value to w's counter. Also, if you reset w's counter, you reset it to v's counter value, not 0. feeling weak and sore all over
