Webconstant factor, and the big O notation ignores that. Similarly, logs with different constant bases are equivalent. The above list is useful because of the following fact: if a function f(n) is a sum of functions, one of which grows faster than the others, then the faster growing one determines the order of f(n).

Weboptimal (up to polylogarithmic factors) in the amount of communication they perform, and just as stable as Householder QR. We prove optimality by deriving new lower bounds for the number of multiplications done by \non-Strassen-like" QR, and using these in known communication lower bounds that are proportional to the number of multiplications. 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. how i spent my vacation tiny toons
