Finding a dominance order most consistent with a linear hierarchy: an improved algorithm for the I&SI method

To find a dominance order most consistent with a linear hierarchy, the I&SI method minimizes two criteria: first the number of inconsistencies I (i.e. number of dyads in which the lower-ranked individual dominates the higher-ranked one) and then (without increasing I) the total strength of inconsistencies SI (i.e. the sum of rank differences between individuals […]
