Be aware that, in practice, a multi-variable criterion is a composite criterion: the OE will instantiate several single-variable criteria, applied on hidden computed variables. For instance, for an alignment criterion between A, B, and C, the OE creates two computed variables (A minus B, and B minus C), and applies a threshold to zero to each of them. When looking at the results, the state of a multi-variable criterion is the worst state among its single-variable criteria.
Alignment Criteria
⚠️ Alignment criteria are deprecated. The better solution is to explicitly model alignments, using spaces with dimensions sharing the same categories (e.g. [product, product]).
