WebMar 16, 2024 · Introduction: A Graph is a non-linear data structure consisting of vertices and edges. The vertices are sometimes also referred to as nodes and the edges are lines or arcs that connect any two nodes in the graph. More formally a Graph is composed of a set of vertices ( V ) and a set of edges ( E ). The graph is denoted by G (V, E). WebApr 6, 2024 · Dijkstra’s algorithm is used to find the shortest path between two points in a weighted graph. It is essential for solving problems such as network routing and mapping.
