Performance of blocking methods for wikipedia (t = 2 and β = 500) and two seed nodes

Blocking method Average number
of nodes affected
with blocking		 Ratio of (average
affected) to (MP
number affected)
CBH 2.0 4.2 × 10−4
PBH 2.0 4.2 × 10−4
Random (RCH) 4187.3 0.87
High degree (HCH) 1882.8 0.39
Betweenness centrality (BCH) 2337.2 0.49
Eigenvector centrality (ECH/HITS) 1885.6 0.39
NetShield 1876.6 0.39

The maximum number of nodes that can be affected from t = 2 diffusion for wikipedia is 4786
