WebOn the other hand, the best uniform complexity does not imply a lower bound on circuit complexity as there is overhead also in the reverse direction, i.e. there can be circuits of size O ( n lg n) even if there is no TM with that running time for multiplication. – Kaveh Jun 2, 2014 at 19:52 Show 7 more comments 1 Answer Sorted by: 2 WebFixed-polynomial size circuit lower bounds. Given the di culty of proving stronger lower bounds for problems in NP, a natural research direction is to investigate super-linear and xed-polynomial circuit size lower bounds for problems in larger complexity classes.
