🔸 Introduction to Dijkstra's Algorithm

Dijkstra's Algorithm allows you to calculate the shortest path between one node (you pick which one) and every other node in the graph.

This calculator uses dijkstra's algorithm, which follows the pseudo-code below. dijkstra(){ V_P ← Ø, V_T ← {all nodes} for(i ∈ {all nodes}) d[i] = (i == s ? 0 : ∞) for(i ∈ {all nodes}) pre[i] ← (i == s ? s : Ø) while(V_P != {all nodes}){ Select i ∈ V_T such that d[i] is minimum V_P = V_P ∪ {i}

The O((V+E) log V) Dijkstra's algorithm is the most frequently used SSSP algorithm for typical input: Directed weighted graph that has no negative weight edge at all, formally: ∀ edge(u, v) ∈ E, w(u, v) ≥ 0. Such weighted graph is very common in real life as travelling from one place to another always use positive time unit(s).

Dijkstra's algorithm is an iterative algorithm that finds the shortest path from source vertex to all other vertices in the graph.

Dijkstra’s algorithm, published in 1959 and named after its creator Dutch computer scientist Edsger Dijkstra, can be applied on a weighted graph. The graph can either be directed or undirected. One stipulation to using the algorithm is that the graph needs to have a nonnegative weight on every edge.
