More broadly-aimed generators might make use of invertible grammars, ones formulated in rule-to-rule fashion and allowing transduction from logical forms to surface forms in much the same way as the "forward" transduction from surface phrase structure to logical form.
This seems to include not only the sentences whose surface logical form would be of the required sort but also those that can be got from such logical truths by making substitutions that were conceptually equivalent.
DETROIT SYMPHONY ORCHESTRA To single out the oddest of the Spring for Music programs: Leonard Slatkin conducts Ives's Symphonies Nos. 1 through 4, a notion utterly logical on its surface yet, given the ear-twisting complexities in much of the music, utterly bizarre.
At any rate, as the history of semantics has shown, it would be foolishly naive to think that ordinary language displays its logical form on its surface.
Eliminating the need to bookkeep logical connections between neighboring surface elements greatly simplifies the Lagrangian tracking of interfaces, particularly for 3D flows exhibiting topology change.
Ever since Microsoft distressed its desktop Windows OEMs by unveiling its own-brand tablet PC, called Surface, the logical leap required to imagine an own-brand Windows Phone has apparently been shrinking.
Participants consistently perceived that the wide straps better cushioned the load borne by the straps, which is logical considering the greater surface area over which to distribute the load generated at the bra strap-shoulder interface.
Accordingly, the finding that the increase in U-Hg was greater for each additional posterior occlusal surface is logical because these surfaces are used for chewing and biting.
Indeed this sort of consideration is most prominent in Davidson (1980b), who seeks the logical form of such surface-binary utterances.
