摘要
Uncoordinated individuals in human society pursuing their personally optimal strategies do not always achieve the 社會 optimum, the most beneficial state to the society as a whole. Instead, strategies form Nash equilibria which are often 社會ly suboptimal. Society, therefore, has to pay a price of anarchy for the lack of coordination among its members. Here we assess this price of anarchy by analyzing the travel times in road 網絡s of several major cities. Our simulation shows that uncoordinated drivers possibly waste a considerable amount of their travel time. Counterintuitively, simply blocking certain streets can partially improve the traffic conditions. We analyze various complex 網絡s and discuss the possibility of similar paradoxes in physics.
