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

Blocking method Average number
of nodes affected
with blocking		 Ratio of (average
affected) to (MP
number affected)
CBH 3.0 8.0 × 10−5
PBH 306.1 8.2 × 10−3
Random (RCH) 34437.7 0.92
High degree (HCH) 25712.3 0.69
Betweenness centrality (BCH) 25896.2 0.69
Eigenvector centrality (ECH/HITS) 26585.5 0.71
NetShield 27119.1 0.73

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