Questão 2

Select one correct alternative about the BFS algorithm: 

a) BFS uses a stack to store the vertices to be explored.

b) A BFS can be used to find a path from one vertex to another in an unweighted graph, but it does not guarantee that this path is the shortest possible.

c) A BFS can be used in undirected unweighted graphs to determine the distance between an initial vertex and all other vertices that make up the same connected component.

d) A BFS is used in weighted graphs to determine the shortest path between a vertex and all others.

e) None of the above.

Questão 6

 In a network, degree correlation describes the tendency of nodes with similar degrees to connect with each other. Which of the following best describes a network with positive degree correlation ? A. High-degree nodes primarily connect with low-degree nodes, leading to a decentralized structure. B. High-degree nodes are more likely to connect with other high-degree nodes, creating tightly connected hubs. C. Low-degree nodes only connect to high-degree nodes, increasing network centralization. D. Low-degree nodes avoid connecting with both low- and high-degree nodes, making the network sparse. E. None of the above. Original idea by: João Augusto Ferreira de Moura
