Could it be the threads accessing the adjacency list data structure in an uncoordinated manner? If one thread could re-use the information loaded in the cache by another thread, it will be better. This could be investigated. Note: As perthe answer here, the steps used...
Assuming that you are using an adjacency list for storing your graph. Breadth-First-Search(Graph, root): 2 3 for each node n in Graph: 4 n.distance = INFINITY 5 n.parent = NIL 6 7 create empty queue Q 8 9 root.distance = 0 10 Q.enqueue(root) 11 12 while Q is not empty: 13...
在BFS算法中,节点和弧是用来描述图的数据结构中的概念。 节点(Node)是图中的一个元素,代表一个实体或对象。在BFS算法中,节点可以是图中的顶点(Vertex)或其他数据结构中的元素。节点可以有不同的属性和关联关系,用于描述实体之间的关系。 弧(Arc)是节点之间的连接线,也称为边(Edge)。弧表示节点之间的关系或连接...

the first being an adjacency matrix (effective with dense graphs) and second an adjacency list (effective with sparse graphs). I have opted to implement an adjacency list which stores each node in a dictionary along with a set containing their adjacent nodes. As the graph is undirected each ...
Preface BFS（Breath-First Search，⼴度优先搜索）与DFS（Depth-First Search，深度优先搜索）是两种针对树与图数据结构的遍历或搜索算法，在树与图相关算法的考察中是⾮常常见的两种解题思路。Definition of DFS and BFS DFS的:Depth-first search (DFS) is an algorithm for traversing or searching tree or ...
