在交通和通信网络中的Braess Paradise（BP）是一个强有力的说明，可能违反直觉的影响纳什均衡解决方案。它表明，矛盾的是，当一个或多个链接被添加到一个加权网络的线性成本取决于拥挤，试图改善它，每个用户独立地寻求她的最佳可能的路线，然后所有用户的旅行的均衡成本可能会增加。扩展了Rapoport等人（2005）的先前研究，我们报告了一项新实验的结果，该实验具有更丰富的拓扑结构和非对称的旅行链路成本，旨在评估BP的描述能力。我们的研究结果表明，经验遍历网络玩家的选择频率接近均衡解所暗示的BP。
The Braess Paradox (BP) in traffic and communication networks is a powerful illustration of the possible counterintuitive implications of the Nash equilibrium solution. It shows that, paradoxically, when one or more links are added to a weighted network with linear costs that depend on congestion with an attempt to improve it, and each user independently seeks her best possible route, then the equilibrium cost of travel of all users may increase. Extending previous research by Rapoport et al. (2005), we report the results of a new experiment with a richer topology and asymmetric link costs of travel designed to assess the descriptive power of the BP. Our results show that with experience in traversing the network players' choice frequencies approach the equilibrium solution as implied by the BP.
