The Minimum Circuit Size Problem (MCSP) asks if a given truth table of a Boolean functionfcan be computed by a Boolean circuit of size at most θ, for a given parameter θ. We improve several circuit lower bounds for MCSP, using pseudorandom generators (PRGs) that are local; a PRG is calledlocalif its output bit strings, when viewed as the truth table of a Boolean function, can be computed by a Boolean circuit of small size. We get new and improved lower bounds for MCSP that almost match the best-known lower bounds against several circuit models. Specifically, we show that computing MCSP, on functions with a truth table of lengthN, requires•N3−o(1)-size de Morgan formulas, improving the recentN2−o(1)lower bound by Hirahara and Santhanam (CCC, 2017),•N2−o(1)-size formulas over an arbitrary basis or general branching programs (no non-trivial lower bound was known for MCSP against these models), and• 2Ω(N1/(d+1.01))-size depth-dAC0circuits, improving the (implicit, in their work) exponential size lower bound by Allender et al. (SICOMP, 2006).The AC0lower bound stated above matches the best-known AC0lower bound (for PARITY) up to a smalladditiveconstant in the depth. Also, for the special case of depth-2 circuits (i.e., CNFs or DNFs), we get an optimal lower bound of 2Ω(N)for MCSP.
