Dijkstra algorithm in java gfg

WebDijkstra's algorithm will begin choosing the edge 1-2 (7). I does so because it is the minimum it has seen so far. It then sets the value of the shortest path to 2 as 7. It will never change this value again, because any other path from 1 to 2 must be larger (as it must start with one of the edges 1-3 (9) or 1-6 (14)). WebJul 12, 2024 · /** * Dijkstra's algorithm. * In essence, Dijkstra's algorithm maintains two sets: one set of nodes whose * distance from source is NOT finalized, one set of nodes whose distance * from source IS finalized. * In implementation, we keep track of the two sets explicitly or implicitly.
