technology and computing artificial intelligence# How do I find the shortest path in Dijkstra?

Last Updated: 3rd May, 2020

**We step through Dijkstra's algorithm on the graph usedinthe algorithm above:**

- Initialize distances according to the
**algorithm**. - Pick first node and
**calculate**distances toadjacentnodes. - Pick next node with minimal distance; repeat adjacentnodedistance calculations.
- Final result of
**shortest**-**path**tree.

Likewise, people ask, what are the shortest path algorithms?

As the **shortest path** will be a concatenationofthe **shortest path** from to , then from to .Time**Complexity** of Floyd–Warshall's **Algorithm** isO (V 3 ) , where is the number of vertices ina**graph**.

what is single source shortest path problem? In graph theory, the **shortest path problem** isthe**problem** of finding a **path** between two vertices(ornodes) in a graph such that the sum of the weights ofitsconstituent edges is minimized.

Similarly, it is asked, does A * find the shortest path?

The A* Algorithm# A* is the most popular choice for pathfinding,becauseit's fairly flexible and **can** be used in a wide rangeofcontexts. A* is like Dijkstra's Algorithm in that it **can**beused to **find** a **shortest path**.

What do you mean algorithm?

An **algorithm** (pronounced AL-go-rith-um) isaprocedure or formula for solving a problem, based on conductingasequence of specified actions. A computer program **can**beviewed as an elaborate **algorithm**. In mathematicsandcomputer science, an **algorithm** usually **means** asmallprocedure that solves a recurrent problem.
