Weighted complex network analysis of travel routes on the Singapore public transportation system

Soh, Harold; Lim, Sonja; Zhang, Tianyou; Fu, Xiuju; … - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 24, pp. 5852-5863

The structure and properties of public transportation networks have great implications for urban planning, public policies and infectious disease control. We contribute a complex weighted network analysis of travel routes on the Singapore rail and bus transportation systems. We study the two...

Statistical properties of weighted complex networks characterized by metaweights

Furuya, Shuhei; Yakubo, Kousuke - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 6, pp. 1265-1272

We propose several characterizations of weighted complex networks by incorporating the concept of metaweight into the clustering coefficient, degree correlation, and module decomposition. These incorporations make it possible to describe weighted networks depending on how strongly we emphasize...

A packet routing strategy using neural networks on scale-free networks

Naganuma, Yuki; Igarashi, Akito - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 3, pp. 623-628

We propose a dynamic packet routing strategy by using neural networks on scale-free networks. In this strategy, in order to determine the nodes to which the packets should be transmitted, we use path lengths to the destinations of the packets, and adjust the connection weights of the neural...

Evolutionary ultimatum game on complex networks under incomplete information

Bo, Xianyu; Yang, Jianmei - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 5, pp. 1115-1123

This paper studies the evolutionary ultimatum game on networks when agents have incomplete information about the strategies of their neighborhood agents. Our model assumes that agents may initially display low fairness behavior, and therefore, may have to learn and develop their own strategies...
