A first plurality of relational tables is obtained from a relational database. Each table of the first plurality of relational tables stores connectivity information for a graph that comprises a plurality of nodes and a plurality of edges connecting the nodes, and each of the nodes is assigned ...
Breadth First Search (BFS) algorithm traverses a graph in a breadthward motion to search a graph data structure for a node that meets a set of criteria. It uses a queue to remember the next vertex to start a search, when a dead end occurs in any iteration....
DFS will try to start from every non-visited node in the graph and starts from that node and obtains a sequence of visited nodes for each starting node. Consequently, the functionbfsreturns avector<GraphNode*>while the functiondfsreturns

In this passage, we use adjacency lists to represent a graph. Specifically, we define the node of the graph to be the following structure: 1structGraphNode {2intlabel;3vector<GraphNode*>neighbors;4GraphNode(int_label) : label(_label) {}5}; ...

In subject area: Computer Science Graph traversal is the process of exploring vertex values in a graph data structure, often limited by memory bandwidth. Strategies like vertex-centric push and pull parallelization, edge-centric parallelization, and the use of frontiers are employed to efficiently nav...
