We give a very simple proof of a 7n=3 c lower bound on the ... 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 north koreans in south korea
