Computation of PBC distances: a numerical example. This example illustrates the computation of PBC distances: (a) distances between the associates A1 to A6; (b) distribution of the associates on the hosts H1 and H2; (c) reduced matrix including in the rows associates of host H1 only and associates of host H2 only in the columns. The row minima are 2, 0, and 2; the column minima are 2, 0, 6, and 6. The PBC distance between H1 and H2 is (2+0+2+2+0+6+6)/(3+4) = 18/7 = 2.571.
