Algorithms for comparisons
To make a pairwise comparison, you need two algorithms:
the Order of the Comparisons algorithm, which determines the order in which the comparisons are displayed in the Pairwise Comparisons frame
See The Order of the Comparisons algorithm.
the Priorities algorithm, which calculates the priorities that are displayed in the charts.
See The Priorities algorithm.
