This is also the same as uniform cost search. WebIf you think of Dijkstra's as "Breadth-first search for weighted graphs," it becomes fairly easy to understand. To answer your questions: 1. Not quite - it's the minimum of the edges traversed to far. 2. Just like with BFS, if it's not adjacent to a visited node, then it can't be visited quite yet. coffeewood correctional center news
