5.2 Different Underlying Topologies
In Figure 4(a)we examine an overlay graph on the more realistic transit-stub topology. The trends for the PoA , O PoA, and Ratio are similar to the results for the line topology, with a peak in PoA at α = 0.8 due to maximal undersupply.
In Figure 5(a) we examine an overlay graph on the power-law topology. We observe several interesting differences between the power-law and transit-stub results. First, the PoA peaks at a lower
