WebThe Dijkstra algorithm goes through these steps: The router builds a graph of the network and identifies source and destination nodes, as V1 and V2 for example. Then it builds a matrix, called the "adjacency matrix." In this matrix, a coordinate indicates weight. For example, [i, j] is the weight of a link between Vi and Vj. WebWe'll see the best approach in the next tutorial called the "Shunting yard algorithm" by Dijkstra. 3. Using Shunting Yard algorithm: Generally, this algorithm is used to convert an infix expression to postfix also known as Reverse Polish notation (RPN). An expression of the format a + b is an infix notation while the format ab+ is its postfix ...
