Question 6 - Network Robustness

 Consider a scale-free network of Protein Interactions, with average degree of 2.9, second moment of 32.3, and degree exponent of 2.89. It is possible to affirm that:


A. The preferential attachment property is valid, with a probability Π(k) that a link of a new node links to another node of degree k proportional to the square of k.


B. This network is perfectly assortative, with a degree correlation coefficient r of 1.


C. This network displays enhanced robustness since its breakdown threshold of value 0.9 is grater than the breakdown threshold of random network prediction of value 0.65. 


D. This network is in a random network regime, since the degree exponent is close to 3.


E. None of the above.

Question 4 - The Barabási-Albert Model

Imagem
Consider the following graph. According to the Linearized Chord Diagram, what are the probabilities that a new node is added to each of the nodes? Consider the normalization constant as 13. A. N1: p =  1/25, N2: p = 4/25, N3: p = 3/25, N4: p = 2/25, N5: p = 1/25, N6: p = 1/25 B. N1: p =  1/13, N2: p = 4/13, N3: p = 3/13, N4: p = 2/13, N5: p = 1/13, , N6: p = 1/13 C.  N1: p =  1/25, N2: p = 4/13, N3: p = 3/13, N4: p = 2/13, N5: p = 1/25, N6: p = 1/25 D. N1: p =  1/3, N2: p = 4/9, N3: p = 3/7, N4: p = 2/5, N5: p = 1/3, N6: p = 1/3 E. None of the above.  Original idea by: Vitoria D. M. Pinho

Question 5 - Envolving Networks

 Choose the correct alternative about evolving network models:  A. In the Bianconi-Barabási Model, the preferential attachment is proportional to the node's degree and fitness property, which is the probability of generating new internal links between pre-existing nodes. B. In the Initial Attractiveness Model, the preferential attachment is proportional to the product of the node degree and a constant A, called initial attractiveness.  C. In the Accelerated Growth Model, for any θ value, the network is always scale-free. D. In the Aging Model, the preferential attachment depends on a v parameter. A positive ν means that new nodes are more likely to connect to younger nodes, while a negative v means that new nodes are more likely to connect to older nodes. E. None of the above.  Original idea by: Vitoria D. M. Pinho
