The shortest path problem can be defined for graphs whether undirected, directed, or mixed. It is defined here for undirected graphs; for directed graphs the definition of path requires that consecutive vertices be connected by an appropriate directed edge. Two vertices are adjacent when they are both incident to a common edge. A path in an undirected graph is a sequence of vertices such that is adjacent to for .

SpletIt is a shortest path problem where the shortest path from all the vertices to a single destination vertex is computed. By reversing the direction of each edge in the graph, this problem reduces to single-source shortest path problem. Dijkstra’s Algorithm is a famous algorithm adapted for solving single-destination shortest path problem.
