In graph theory (and its applications) it is often required to model how information spreads within a given graph. This is interesting for many applications, such as attack prediction, sybil... 宽度优先遍历BFS和深度优先遍历DFS 宽度优先遍历:又叫广度优先遍历 就是离头节点最近的节点先输出,按层次输...
We find that the bias gets amplified in graphs with strong positive assortativity. Finally, we demonstrate the above results by sampling the Facebook social network, and we provide some practical guidelines for graph sampling in practice. 展开 关键词:...

Standard breadth-first search (BFS) is an algorithm for finding nodes from a starting node or nodes in a graph in breadth-first order. It returns the source node or nodes that it started from, and all of the nodes visited by each search. Note Because every source node passed in leads ...
We can extend this even further if we allow the weights of the edges to be even bigger. If every edge in the graph has a weight ≤k<math xmlns="http://www.w3.org/1998/Math/MathML"><mo>≤</mo><mi>k</mi></math>$\le k$ , then the distances of vertices in the queu...

For each v in the G[u]: If colour[v] is WHITE, perform: set colour[v] = GRAY distance[v] = distance[u] + 1 parent[v] = u Enqueue v to the queue colour[u] = BLACK Lets us again discuss the algorithm with an example. Suppose you are given the below graph: ...
