The simplest implementation of the Dijkstra's algorithm stores vertices of set Q in an ordinary linked list or array, and extract minimum from Q is simply a linear search through all vertices in Q. In this case, the running time isO(|E|+|V|2)=O(|V|2)O(|E|+|V|2)=O(|V|2). ...
(WAN for example) according to specifications, the routing system must assign to the network the best and optimal path in order to avoid the congestion phenomenon.In this paper, we suggest a new approach for the implementation of the DIJKSTRA routing algorithm by using an FPGA development card ...
I used dijkstra algorithm to solve it. I generally use the template from here, but in this question, this implementation gave me WA. When I used another implementation using visited array, it gave AC. WA code AC Code Naturally, I adopted the visited array approach and discarded the one ...

Normally in a Dijkstra implementation, a node is only repeated if the algorithm found a shorter distance for it, so no two distances are the same. Also, due to how priority queue works, the first time you visit that node would have the distance information being exactly the best value (th...
