Calculate shortest paths in Java by implementing Dijkstra’s Algorithm
Conceived by Edsger W. Dijsktra in 1956 and published three years later, Dijkstra’s algorithm is a one of the most known algorithms for finding the shortest paths between nodes in a graph. This algorithm is applied in a lot of domains. For example, once you have represented road networks in a graph, it becomes easy to calculate shortest paths inside…
