Algorithms for minimization without derivatives
by R. P Brent
(
Book
)
17 editions published between 1972 and 2013 in English and held by 539 WorldCat member libraries worldwide Outstanding text for graduate students and research workers proposes improvements to existing algorithms, extends their related mathematical theories, and offers details on new algorithms for approximating local and global minima. Many numerical examples, along with complete analysis of rate of convergence for most of the algorithms and error bounds that allow for the effect of rounding errors
Modern computer arithmetic
by R. P Brent
(
Book
)
11 editions published between 2010 and 2011 in English and held by 216 WorldCat member libraries worldwide "Modern Computer Arithmetic focuses on arbitraryprecision algorithms for efficiently performing arithmetic operations such as addition, multiplication and division, and their connections to topics such as modular arithmetic, greatest common divisors, the Fast Fourier Transform (FFT), and the computation of elementary and special functions. Brent and Zimmermann present algorithms that are ready to implement in your favorite language, while keeping a highlevel description and avoiding too lowlevel or machinedependent details. The book is intended for anyone interested in the design and implementation of efficient highprecision algorithms for computer arithmetic, and more generally efficient multipleprecision numerical algorithms. It may also be used in a graduate course in mathematics or computer science, for which exercises are included. These vary considerably in difficulty, from easy to small research projects, and expand on topics discussed in the text. Solutions are available from the authors."Publisher's website

A systolic algorithm for integer GCD computation

Book
)
7 editions published between 1982 and 1984 in English and Undetermined and held by 9 WorldCat member libraries worldwide Abstract: "We show that the greatest common divisor of two nbit integers (given in the usual binary representation) can be computed in time O(n) on a linear array of O(n) identical systolic cells, each of which is a finitestate machine with connections to its nearest neighbours."
Analysis of the binary Euclidean algorithm
by R. P Brent
(
Book
)
2 editions published in 1976 in English and held by 9 WorldCat member libraries worldwide In this paper the author analyzes a continuous model of the binary algorithm and finds the expected number of iterations. The results agree with the observed behavior of the algorithm much better than those predicted by Knuth's 'latticepoint' model

Improved techniques for lower bounds for odd perfect numbers
by R. P Brent
(
Book
)
6 editions published in 1989 in English and held by 8 WorldCat member libraries worldwide Abstract: "If N is an odd perfect number, and q[superscript k] [symbol] N, q prime, k even, then it is almost immediate that N> q[superscript 2k]. We prove here that, subject to certain conditions verifiable in polynomial time, in fact N> q[superscript 5k/2]. Using this and related results, we are able to extend the computations in an earlier paper to show that N> 10[superscript 300]."

The areatime complexity of Binary multiplication
by R. P Brent
(
Book
)
3 editions published in 1979 in English and Undetermined and held by 7 WorldCat member libraries worldwide We consider the problem of performing multiplication of nbit binary numbers on a chip. Let A denote the chip area, and T the time required to perform multiplication. Using a model of computation which is a realistic approximation to current and anticipated VLSI technology, we show that (A/A sub 0) (T/T sub 0) to the 2 alpha power> or = n to the (1 + alpha) power for all alpha is an element (0, 1), where A sub 0 and T sub 0 are positive constants which depend on the technology but are independent of n. The exponent 1 + alpha is the best possible. A consequence is that binary multiplication is 'harder' than binary addition if AT to the 2 alpha power is used as a complexity measure for any alpha> or = 0. (Author)

A class of optimalorder zerofinding methods using derivative evaluations
by R. P Brent
(
Book
)
2 editions published in 1975 in English and held by 5 WorldCat member libraries worldwide It is often necessary to find an approximation to a simple zero zeta of a function f, using evaluations of f and f' . In this paper the author considers some methods which are efficient if f' is easier to evaluate than f . Examples of such functions are given

Fast algorithms for manipulating formal power series
by R. P Brent
(
Book
)
2 editions published in 1976 in English and held by 5 WorldCat member libraries worldwide The classical algorithms require O(n sup 3) operations to compute the first n terms in the reversion of a power series or the composition of two series, and O((n sup 2) log n) operations if the fast Fourier transform is used for power series multiplication. In this paper we show that the composition and reversion problems are equivalent (up to constant factors), and we give algorithms which require only O((n log n) sup 3/2) operations. In many cases of practical importance only O(n log n) operations are required. An application to rootfinding methods which use inverse interpolation is described, some results on multivariate power series are stated, and several open questions are mentioned more
