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

Blocking method Average number
of nodes affected
with blocking		 Ratio of (average
affected) to (MP
number affected)
CBH 2.0 5.4 × 10−5
PBH 2.0 5.4 × 10−5
Random (RCH) 32373.0 0.87
High degree (HCH) 20627.7 0.55
Betweenness centrality (BCH) 18809.3 0.50
Eigenvector centrality (ECH/HITS) 22105.1 0.59
NetShield 20929.2 0.56

The maximum number of nodes that can be affected from t = 2 diffusion for epinions is 37300
