An Efficient Immunization Strategy for Community Networks

Kai Gong, Ming Tang, Pak Ming Hui, Hai Feng Zhang, Do Younghae, Ying-Cheng Lai, Attila Szolnoki
2013 PLoS ONE  
Typically, a population is characterized by its community structure and the heterogeneity in the weak ties among nodes bridging over communities.  ...  The effectiveness stems from the breaking up of community networks by successful searches on target nodes with more weak ties.  ...  The algorithm does not require any information about the degree of the nodes. It is efficient for large networks with a broad degree distribution.  ...
