Weba polylogarithmic factor better than cubic [1], we cannot obtain preprocessing time better than n3/2 and query time better than √ n simultaneously by purely combinatorial techniques with current knowledge, except for polylogarithmic-factor speedups. In view of the above hardness result, it is therefore worthwhile to pursue more modest WebThe problems of random projections and sparse reconstruction have much in common and individually received much attention. Surprisingly, until now they progressed in parallel and remained mostly separate. Here, we empl…

WebWe essentially close the question by proving an Ω ( t 2) lower bound on the randomness complexity of XOR, matching the previous upper bound up to a logarithmic factor (or constant factor when t = Ω ( n) ). We also obtain an explicit protocol that uses O ( t 2 ⋅ log 2 n) random bits, matching our lower bound up to a polylogarithmic factor. WebDec 3, 2024 · We show that with high probability G p contains a complete minor of order $\tilde{\Omega}(\sqrt{k})$ , where the ~ hides a polylogarithmic factor. Furthermore, in the case where the order of G is also bounded above by a constant multiple of k, we show that this polylogarithmic term can be removed, giving a tight bound.

In mathematics, the polylogarithm (also known as Jonquière's function, for Alfred Jonquière) is a special function Lis(z) of order s and argument z.
