Dijkstra Algorithm in Java Baeldung

WebThe algorithm was developed by a Dutch computer scientist Edsger W. Dijkstra in 1956. It is used to find the shortest path between a node/vertex (source node) to any (or every) other nodes/vertices (destination nodes) in a graph. A graph is basically an interconnection of nodes connected by edges. This algorithm is sometimes referred to as ... WebA variant of this algorithm is known as Dijkstra’s algorithm. Dijkstra’s Algorithm is an algorithm for finding the shortest paths between nodes in a graph. For a given source node in the graph, the algorithm finds the shortest path between that node and every other node.
