WebJun 8, 2024 · The fast Fourier transform is a method that allows computing the DFT in O ( n log n) time. The basic idea of the FFT is to apply divide and conquer. We divide the coefficient vector of the polynomial into two vectors, recursively compute the DFT for each of them, and combine the results to compute the DFT of the complete polynomial.

Web‡ This algorithm was the asymptotically fastest known method to multiply until in 2007 Fürer [Fü07] found an even faster way. Asymptotically means that the algorithm was the fastest, provided numbers are long enough. Elaborate algorithms often involve some costs for set-up that only pay off if the inputs are long enough.§ bulk sugar cane juiceUsage in computers.
