The algorithm creates a tree of shortest paths from the starting vertex, the source, to all other points in the graph. Dijkstra’s algorithm, published in 1959 and named after its creator Dutch computer scientist Edsger Dijkstra, … officeserve hofmannSpletDijkstra algorithm is a single-source shortest path algorithm. Here, single-source means that only one source is given, and we have to find the shortest path from the source to all the nodes. Let's understand the working of Dijkstra's algorithm. Consider the below graph. First, we have to consider any vertex as a source vertex. my dog ate a bone and is throwing up

"SpletDijkstra's algorithm finds all the shortest paths from the source vertex to every other vertex by iteratively ``growing'' the set of vertices S to which it knows the shortest path. At each step of the algorithm, the next vertex added to S is determined by a priority queue. " - Shortest path using dijkstra's algorithm c++
