异质路由博弈中用户均衡的稳定性

On stability of users equilibria in heterogeneous routing games

Leonardo Cianfanelli, Giacomo Como

摘要:

分析了异质路由博弈中确定性logit动态的渐近行为。证明了在具有平行路线的有向多重图中,以及在这类多重图的串联合成中,动力学存在一个全局渐近稳定的不动点。此外,唯一的不动点的动力学接近Wardrop平衡集,噪声消失。该结果依赖于这样一个事实,即聚合流的动力学是单调的,其雅可比矩阵是严格对角占优的列。

英文摘要:

The asymptotic behaviour of deterministic logit dynamics in heterogeneous routing games is analyzed. It is proved that in directed multigraphs with parallel routes, and in series composition of such multigraphs, the dynamics admits a globally asymptotically stable fixed point. Moreover, the unique fixed point of the dynamics approaches the set of Wardrop equilibria, as the noise vanishes. The result relies on the fact that the dynamics of aggregate flows is monotone, and its Jacobian is strictly diagonally dominant by columns.
