About
Dijkstra's algorithm is used for finding shortest paths from start vertex in graph(with weighted vertices) to all other vertices. More algorithm's description can be found in playground or on wikipedia: Wikipedia
To understand how does this algorithm works, I have created VisualizedDijkstra.playground. It works in auto and interactive modes. Moreover there are play/pause/stop buttons.
If you need only realization of the algorithm without visualization then run Dijkstra.playground. It contains necessary classes and couple functions to create random graph for algorithm testing.
