WebL' algorithme Toom-Cook, parfois appelé Toom-3, est un algorithme de multiplication dû à Andrei Toom (en) et Stephen Cook, utilisé pour multiplier deux grands nombres. Ces grands nombres sont découpés en k morceaux de longueur l sur lesquels les multiplications sont faites récursivement à la manière d’un diviser pour régner.

WebToom-Cook 3-Way Multiplication. The Karatsuba formula is the simplest case of a general approach to splitting inputs that leads to both Toom-Cook and FFT algorithms. A description of Toom-Cook can be found in Knuth section 4.3.3, with an example 3-way calculation after Theorem A. The 3-way form used in GMP is described here. WebKaratsuba and Toom-3 split the operands into 2 and 3 coefficients, Toom-4 analogously splits the operands into 4 coefficients. polynomials: X(t) = x3*t^3 + x2*t^2 + x1*t + x0Y(t) = …
