AbstractWe show that every languageL in the class ACC can be recognized by depth-two deterministic circuits with a symmetric-function gate at the root and
$$2^{\log ^{O(1)} n} $$
AND gates of fan-in logO(1)n at the leaves, or equivalently, there exist polynomialspn(x1,..., xn) overZ of degree logO(1)n and with coefficients of magnitude
$$2^{\log ^{O(1)} n} $$
and functionshn:Z→{0,1} such that for eachn and eachx∈{0,1}n,XL(x)=hn(pn(x1,...,xn)). This improves an earlier result of Yao (1985). We also analyze and improve modulus-amplifying polynomials constructed by Toda (1991) and Yao (1985).
