In a scale-free network with 8,000 nodes, 10% of the nodes have a degree of 10 or more. If the degree exponent γ is 2, what is the approximate percentage of nodes with a degree of 5 or more?


a. 40%

b. 20%

c. 50%

d. 30%

e. None of the above.

    Wonderful question. I loved it. I used the continuous formalism. From the 10% figure we find out the value of k_min, and the use that to find the answer. Very beautiful. In the official blog, I changed a bit the order of alternatives.

In an evolving network following the Barabási-Albert model, there are two nodes - node C with a degree of 15, and node D with a degree of 25. Given the preferential attachment characteristic of the model, how much more likely is a new node to connect to D than to C? A. 0.6 times more likely B. 1.6 times more likely C. 2.5 times more likely D. 1.7 times more likely E. None of the above Original idea by: Olalekan Sadeeq Bello
