WebPrior work relies on other lower bounds such as the nondeterministic time hierarchy theorem or MA/1 circuit lower bounds, and neither results are known to hold almost-everywhere. If we knew (for example) NTIME[ ] is not infinitely often in NTIME[ / ( )], then we could conclude some kind of almost-everywhere lower bound.

Circuit Lower Bounds from #SAT Algorithms: Williams’ paradigm [Wil13,Wil14, MW18] for lower bounds gives circuit lower bounds from circuit satisfiability algorithms. We build upon this paradigm and study lower bounds that can be obtained from algorithms which count the number of satisfying solutions for a circuit i.e. #SAT algorithms.
