The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License. The library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting. There are over 1000 functions in total with an extensive test suite. The current version is GSL-1.8. It was released on 10 April 2006. This is a stable release. The complete range of subject areas covered by the library includes, See less

FFTW 3.1.2 is the latest official version of FFTW (refer to the release notes to find out what is new). Subscribe to the fftw-announce mailing list to receive announcements of future updates. Here is a list of some of FFTW's more interesting features: * Speed. (Supports SSE/SSE2/3dNow!/Altivec, since version 3.0.) * Both one-dimensional and multi-dimensional transforms. * Arbitrary-size transforms. (Sizes with small prime factors are best, but FFTW uses O(N log N) algorithms even for prime sizes.) * Fast transforms of purely real input or output data. * Transforms of real even/odd data: the discrete cosine transform (DCT) and the discrete sine transform (DST), types I-IV. (Version 3.0 or later.) * Efficient handling of multiple, strided transforms. (This lets you do things like transform multiple arrays at once, transform one dimension of a multi-dimensional array, or transform one field of a multi-component array.) * Parallel transforms: parallelized code for platforms with Cilk or...

MAXIMA 对字母的大小写是不敏感的: 不管你输入的是 sin(x) 还是 SIN(x), 是 %e^x 还是 %E^x, 它都会明白你的意思是正弦函数和指数函数, 然后按标准的方式回显大写的 SIN 和 %E. 以上对用户定义的变量并不成立, 即: x and X 对于 MAXIMA 是 不一样的 变量! (试试看.) See less

A genetic or evolutionary algorithm applies the principles of evolution found in nature to the problem of finding an optimal solution to a Solver problem. In a "genetic algorithm," the problem is encoded in a series of bit strings that are manipulated by the algorithm; in an "evolutionary algorithm," the decision variables and problem functions are used directly. Most commercial Solver products are based on evolutionary algorithms. An evolutionary algorithm for optimization is different from "classical" optimization methods in several ways: See less

These pages introduce some of the fundamentals of genetics algorithms. These pages are intended to be used for learning about genetics algorithms without any previous knowledge from this area. Only some knowledge of computer programming is assumed. Several interactive Java applets have been included to demonstrate basic concepts of genetic algorithms. As the area of genetic algorithms is very wide, it is not possible to cover everything in these pages. But you should get some idea what genetic algorithms are and what they could be useful for. Do not expect any sophisticated mathematics theory here. Now please choose next to continue or you can choose any topic from the menu on the left side. If you do not want to read all the introductory chapters, you can skip directly to genetic algorithms and return later. Translations of these pages are also available - you may go to the Japanese translation (translated by Ishii Manabu) or to the Bulgarian translation (translated by Teodor Gig) or... See less
