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
Again, tight bounds are provided, showing that there exists a poly-time algorithm that for every $n$-vertex graph and source set $S \\\subseteq V$ of size $\\\sigma$ constructs a (single failure) FT-MBFS tree $T^*(S)$ from each source $s_i \\\in S$, with $O(\\\sqrt{\...

Problem Description: Given a binary tree, return its node values in level order traversal. That is, nodes at each level are visited from left to right, level by level. Applying BFS: Our starting node is the root of the binary tree. We don't have a specific ending node; we'll cont...
A fully polynomial algorithm has a round complexity in O(da) and a step complexity in O(nb) where d and n are the diameter and the number of nodes of the network and a and b are constants. We present the first fully polynomial stabilizing algorithm constructing a BFS tree under a distr...
Breadth first traversal or Breadth first Search is a recursive algorithm for searching all the vertices of a graph or tree data structure. In this tutorial, you will understand the working of bfs algorithm with codes in C, C++, Java, and Python.

I've written some important Algorithms and Data Structures in an efficient way in Java with references to time and space complexity. These Pre-cooked and well-tested codes help to implement larger hackathon problems in lesser time. DFS, BFS, LCA, LCS, Segment Tree, Sparce Table, All Pair ...
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...
Time Complexity The time complexity of the BFS algorithm is represented in the form of O(V + E), where V is the number of nodes and E is the number of edges. Space Complexity The space complexity of the BFS algorithm is O(V). ...
