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.
