    <p>Compared with <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0139941#pone.0139941.g001" target="_blank">Fig 1</a>, we here calculate the initial load on node 3. When <i>Ξ±</i> = 1, We can get that the loads generated by nodes 0, 1, 2, 3, 4, 5, 6, and 7 are <i>F</i><sub>0</sub> = 1, <i>F</i><sub>1</sub> = 1, <i>F</i><sub>2</sub> = 4, <i>F</i><sub>3</sub> = 2, <i>F</i><sub>4</sub> = 2, <i>F</i><sub>5</sub> = 4, <i>F</i><sub>6</sub> = 1, and <i>F</i><sub>7</sub> = 1, respectively. According to the preferential principle of the destination selection of the load transported, we can calculate the load exchanged between any two nodes. We can further get the loads passing through node 3 in the loads generated by every node are <i>B</i><sub>3,0 β†’</sub> = 3/15, <i>B</i><sub>3,1 β†’</sub> = 3/15, <i>B</i><sub>3,2 β†’</sub> = 1, <i>B</i><sub>3,3 β†’</sub> = 0, <i>B</i><sub>3,4 β†’</sub> = 0, <i>B</i><sub>3,5 β†’</sub> = 1, <i>B</i><sub>3,6 β†’</sub> = 3/15, and <i>B</i><sub>3,7 β†’</sub> = 3/15, respectively. Therefore, we can obtain that the total load <i>B</i><sub>3</sub> transported by node 3 is 2.8, i.e., the initial load <i>L</i><sub>3</sub> on node 3 is 2.8.</p

    <p>In the betweenness method, assume that the load was transmitted along the shortest path between every pair of nodes. If calculating the initial load on a node, we need to count the effect of the load transmitted between all pairs of nodes on this node. For example, we calculate the load on node 3. We use <i>F</i><sub><i>i</i> β†’ <i>j</i></sub> and <i>B</i><sub><i>m</i>, <i>i</i> β†’</sub> to denote the load transported from node <i>i</i> to <i>j</i> and the load passing through node <i>m</i> in all load generated by node <i>i</i>, respectively. By calculating the load passing through node 3 and generated by every node, we get <i>B</i><sub>3,0 β†’</sub> = 1.5, <i>B</i><sub>3,1 β†’</sub> = 1.5, <i>B</i><sub>3,2 β†’</sub> = 1.5, <i>B</i><sub>3,3 β†’</sub> = 0, <i>B</i><sub>3,4 β†’</sub> = 1.5, <i>B</i><sub>3,5 β†’</sub> = 1.5, <i>B</i><sub>3,6 β†’</sub> = 1.5, and <i>B</i><sub>3,7 β†’</sub> = 1.5. Therefore, we can obtain <i>B</i><sub>3</sub> = 9, which represents the total load transported by node 3.</p

    Node degree influences the number of the load generated by this node.

    <p>In the Internet, traffic networks, and the power grid, in general, the bigger the degree of a node, the higher the load generated by it. We define <i>F</i><sub><i>i</i> β†’</sub> to represent the total load generated by node <i>i</i>, which is transported to other nodes in a network. Owing to the effect of the node degree, <i>F</i><sub>0 β†’</sub> should be not equal to <i>F</i><sub>5 β†’</sub>.</p

    <p>Here, pink nodes denote cooperators and blue nodes denote defectors. All the two top nodes’ friends overlap, therefore the tie strength between them equals one. All other relations have a tie strength equals . We set the two mutual best friends as cooperators initially. (a) When , the game is a classical PDG. The two cooperators get a payoff of and all the defectors get . Therefore, cooperators will imitate the strategy of defectors and defection becomes prevalent; (b) When , the two cooperators will invest all their investments to each other. Both cooperators get and all defectors get 0. Therefore, in the next round, all defectors will adopt C and cooperation becomes prevalent.</p
