摘要:
Let X be an n-element set, and let C be a system of subsets of X. A coloring of X is any mapping χ: X → {−1, +1}. The discrepancy of C, denoted by disc(C), is the minimum, over all colorings χ of disc(χ, C) = max |χ(S)| , S∈C, where χ(S) is the sum of χ(x), x∈S. In this talk, we introduce Partial Coloring and Entropy Method to give a classical upper bound of discrepancy of any subsets system C.
