The shortest path algorithm determines the shortest distance between the source and the destination. To solve the shortest path problem, we use a graph. Graph isa abstract notation used to represent the connection between pairs of object. A graph has vertices and edges. Vertex is a node of graph. A graph edge connects one or more graph vertex. Both directed and undirected graphs exist. The formal definition of a graph is a pair of sets, V and E, where V is the set of vertices and E is the set of edges that link the pairs of vertices. Edges in undirected graphs are those without a direction. Each edge can be crossed in both directions, which indicates a two-way link. Edges in directed graphs have a direction. Since each edge can only be crossed once, the edges signify a one-way relationship. Wight, which is used to determine the shortest path from, is contained in edges. from a source to a destination. Think about several maps of airline routes. A direct flight from the airport represented by vertex A to the airport represented by vertex B creates an edge between the two. B's airport is represented. Different shortest path algorithms exist to address the shortest path issue. They are the Genetic Algorithm, Dijkstra's, Floyd-Warshall, Bellman Ford, and algorithms.
