Feb 21, 2023 · Given a directed graph and a source vertex in the graph, the task is to find the shortest distance and path from source to target vertex in the given graph where edges are weighted (non-negative) and directed from parent vertex to source vertices. Recommended: Please try your approach on {IDE} first, before moving on to the solution. Approach:

🔸 Introduction to Dijkstra's Algorithm

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.

• Claim: At end of Dijkstra’s algorithm, d(s, v) = δ(s, v) for all v ∈ V • Proof: – If relaxation sets d(s, v) to δ(s, v), then d(s, v) = δ(s, v) at the end of the algorithm ∗ Relaxation can only decrease estimates d(s, v) ∗ Relaxation is safe, i.e., maintains that each d(s, v) is weight of a path to v (or ∞)

Types of Graphs · Undirected: if for every pair of connected nodes, you can go from one node to the other in both directions. · Directed: if for ...

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.
