Fig. 1From: Sampling on networks: estimating spectral centrality measures and their impact in evaluating other relevant network measuresTCEC sampling visual representation. Consider a candidate node j to be added to the current sample \(G_m\). The algorithm considers: the outgoing connections \(b_1\) towards the sample, the incoming connections \(b_3\) from the non-sampled nodes and U, the remaining edges incoming towards the sampleBack to article page
