    A new characterization of ACC(0) and probabilistic CC0

  • Original language description

    Barrington, Straubing and Therien (1990) conjectured that the Boolean AND function can not be computed by polynomial size constant depth circuits built from modular counting gates, i.e., by CC0 circuits. In this work we show that the AND function can becomputed by uniform probabilistic CC0 circuits that use only O(log n) random bits. This may be viewed as evidence contrary to the conjecture. As a consequence of our construction we get that all of ACC0 can be computed by probabilistic CC0 circuits thatuse only O(log n) random bits. Thus, if one were able to derandomize such circuits, we would obtain a collapse of circuit classes giving ACC0=CC0. We present a derandomization of probabilistic CC0 circuits using AND and OR gates to obtain ACC0 = AND /circ OR /circ CC0 = OR /circ AND /circ CC0. AND and OR gates of sublinear fan-in suffice. Both these results hold for uniform as well as non-uniform circuit classes.
