如果搜索的是tree的话,并且有限,那么显然是complete的。 但是如果是graph的话,如果有环,那么就会一直在这个环里打转转,那么就不是complete的。 如果深度是infinite的话,那么不complete。 complete还有另外一种解释。 optimal: 并不optimal,例子很容易构造: time complexity: space complexity: 4. BFS frontier is firs...

Depth First Search is a recursive algorithm for searching all the vertices of a graph or tree data structure. In this tutorial, you will learn about the depth-first search with examples in Java, C, Python, and C++.
We present an algorithm for a fault tolerant Depth First Search (DFS) Tree in an undirected graph. This algorithm is drastically simpler than the current state-of-the-art algorithms for this problem, uses optimal space and optimal preprocessing time, and still achieves better time complexity. ...

(1) Tree edge iff u discovers v during the DFS: P[v] = u If (u,v) is NOT a tree edge then it is a: (2) Forward edge iff u is an ancestor of v in the DFS tree (3) Back edge iff u is a descendant of v in the DFS tree ...
