Data Smog: Surviving the Information Glut Revised and Updated Edition
Media student ( and net fanatic ) David Shenk examines the troubling results of knowledge proliferation on bodies, our brains, our relations, and our tradition, then bargains strikingly down-to-earth insights for dealing with the deluge. With a skillful mix of own essay, firsthand reportage, and sharp research, Shenk illustrates the valuable paradox of our time: as our international will get extra advanced, our responses to it turn into more and more simplistic.

Indeed, the particular recurrences that we’ve just solved are sufficient to describe the performance of most of the algorithms that we’ll be studying, and we’ll simply be referring back to them. Matrix Multiplication The most famous application of the divide-and-conquer technique to an arithmetic problem is Strassen’s method for matrix multiplication. We won’t go into the details here, but we can sketch the method, since it is very similar to the polynomial multiplication method that we have just studied.
One way to split a polynomial in two is to divide the coefficients in half: given a polynomial of degree N-l (with N coefficients) we can split it into two polynomials with N/2 coefficients (assume that N is even): by using the N/2 low-order coefficients for one polynomial and the N/2 high-order coefficients PoLMvoMIALs 49 for the other. For p(z) = po + pla: + . ‘, define f%(x) =p,, +pla:+“~+pN,2-~xN’2-1 Ph(x) = pN/2 + pN/2+15 -I- ’ ’ * + pN-1xN’2-? Then, splitting q(x) in the same way, we have: P(x) = Pi(x) + zN’2ph(x), q(x) = 41(x) + “N’2qh(x).
The evaluation problem is to find the values, given the polynomial and the points. ) The classic solution to the interpolation problem is given by Lagrange’s interpolation formula, which is often used as a proof that a polynomial of degree N - 1 is completely determined by N points: This formula seems formidable at first but is actually quite simple. s+13s5=j which simplifies to x2 +a:+ 1. For x from xl, x2, . . , XN, the formula is constructed so that p(xk) = yk for 1 5 k 5 N, since the product evaluates to 0 unless j = k, when it evaluates 48 CHAPTER 4 to 1.
