algorithm - Shortest path between two given nodes in unweighted graph/tree -


i looking algorithm determine shortest path between 2 nodes in unweighted graph using adjacency matrix . know dijkstra , bellman - ford, none found specific determine shortest path between 2 given nodes.

any apreciated

one simple option run breadth-first search starting @ first node until second node found. if store parent pointers each node, can read off path first node second. moreover, runs in linear time in size of graph.

hope helps!
