How fast can we compute products?
1999
Proceedings of the 1999 international symposium on Symbolic and algebraic computation - ISSAC '99
Preserved Fulltext
III this paper we consider the problem of fast computation of n-ary products, for large n, over arbitrary precision integer or ra.tional number domains. ...
The combinat.ion of loop unrolling, chains of recurrences techniques and analogs of binary powering allows us to obt.ain order-of-magnitude speed improvements for such computations. ...
III this paper we would like to address a related problem and t,ry to answer the question "how fast we can compute n-ary products for large n?" ...

We provide two complexity measures that can be used to measure the running time of algorithms to compute multiplications of long integers. ...
The Turing machine is more useful here, but fails to take into account the multiplication instruction for short integers, which is available on physical computing devices. ...
But it does not have the practical advantage of real computers, that can do operations like additions of reasonable numbers almost as fast as a bit operation. ...

A fast method for solving a linear system of the form (A (p) ⊗ · · · ⊗ A (1) − λI)x = b is given where each A (i) is an n i -by-n i matrix. ...
The first step is to convert the problem to triangular form (T (p) ⊗ · · · ⊗ T (1) − λI)y = c by computing the (complex) Schur decompositions of the A (i) . ...
Perhaps the best example of this is the fast Fourier transform which can be described using the "language" of sparse, matrix factorizations and the Kronecker product. ...
