In a power grid, we have tree communities: Red, Blue and Purple . As Figure shows (Each node with number represents a power substation) You are at a networking party to meet influential people. At this party, you meet a man running for governor in a state. Based on the power grid topology (on the figure), the politician asks you about the robustness and the sequence of potential attacks on the power grid. Which of the following statements could you said to the politician: Community Purple is more robust, and community Brown is more vulnerable. Community Red has a decentralized topology. Therefore, in a random attack, community Red will be more resilient. In a targeted attack, the sequence of attacks on power substations is : 37,24 and 18 In a targeted attack, the sequence of attacks on power substations is : 7,18 and 25 Chose the right answer. II and III I and III II and IV I and IV None of the above. Original

We have a model that consider the degree distribution formulation in an induced small-degree saturation of evolving networks with initial attractiveness of 12 . For a degree of 20 the degree distribution is 2.98x10 −8 . And when the degree is 52 , the degree distribution is 9.31x10 −10 . Find the degree exponent. γ=5.0 γ=5.25 γ=5.5 γ=5.75 None of the above.
