IfS⊆{0,1};*andS′ = {0,1}*\sbSare both recognized within a certain nondeterministic time boundTthen, in not much more time, one can write down tautologiesAn→A′nwith unique interpolantsInthat defineS∩{0,1}n; hence, if one can rapidly find unique interpolants, then one can recognizeSwithin deterministic timeTpfor some fixedp\s>0. In general, complexity measures for the problem of finding unique interpolants in sentential logic yield new relations between circuit depth and nondeterministic Turing time, as well as between proof length and the complexity of decision procedures of logical theories.
