Ranking and optimality are based on pairwise comparisons between
a desired optimum and its competitors. The 'comparative tableau'
identifies and represents the elements that figure in the logic
of ranking arguments, a prerequisite for the understanding of
optimality-theoretic analyses. As a data-structure, the comparative
tableau makes it straightforward to present and assess claims of
crucial ranking; to find redundancies and contradictions in sets
of ranking arguments; to employ the constraint demotion algorithms;
and to efficiently determine universal suboptimal status.
Appendix added 2/12/2000.
