The Bianconi-Barabási Model

Which of the following statements accurately describes the preferential attachment mechanism in the Bianconi-Barabási model? A) Nodes are added to the network based on a random process without considering the existing nodes' connectivity. B) New nodes connect to existing nodes equally, resulting in a uniform degree distribution. C) Nodes are added to the network based on their fitness, independently of the connectivity of existing nodes. D) New nodes preferentially attach to high-degree nodes, resulting in a power-law degree distribution.  E) None of above Original idea by: Leonardo Henrique de Braz

Network Studies - Barabasi-Albert model

In the context of the Barabasi-Albert model, what is the main difference between a scale-free network and a random network? A) Scale-free networks exhibit a higher clustering coefficient, while random networks exhibit a uniform degree distribution. B) Scale-free networks exhibit an exponential degree distribution, while random networks exhibit a power-law degree distribution. C) Scale-free networks exhibit a power-law degree distribution, while random networks exhibit an exponential degree distribution. D) Scale-free networks and random networks exhibit similar degree distributions but differ in how nodes are connected E) None of the above. Original idea by: Leonardo Henrique de Braz.

Network Question - First Concepts

Imagem
 The figure below is a dependency graph about the discipline requirements in a school. The requirement relationship is defined by a direct link, in which a discipline describes its prerequisite to be attended. For example: Discipline D has discipline A as a prerequisite; and Discipline E has disciplines A and B as a prerequisite. Note: the discipline is a node, the prerequisite is a link, and the image is a network. On the figure, consider the following sentences and mark them as true (T) or false (F): The node with the highest (and only) degree is node M; The nodes A, B, and C do not have prerequisites; Discipline G is a prerequisite for discipline H; The incoming degree for discipline O is 2; The outcoming degree for discipline H is 2; The correct option that matches the sentences is: a) T-T-F-F-T b) F-T-F-F-T c) F-F-T-T-T d) T-T-F-T-F e) none of above Original idea by: Leonardo H. de Braz
