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++.
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...
because itisfaster togetcloser node//If the tree is very deep and solutions are rare:BFS, DFS will take a longer time because of the deepth of the tree//If the tree is very wide:DFS,forthe worse cases, both BFS and DFS time complexityisO(N). ...
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. ...

There are many tree questions that can be solved using any of the above four traversals. Examples of such questions aresize,maximum,minimum,print left view, etc. Is there any difference in terms of Time Complexity? All four traversals require O(n) time as they visit every node exactly once...
of a tree, or any random node(in case of graph) and explore as far as possible in a branch and then come back to a fixed point. DFS is generally used for connectivity questions. It has a time complexity ofO(N+E)WhereNis the total number of nodes andEis the total number of edges....
