ARMR provides a foundation for creating an efficient in-memory database. Its unique list processing structures simplify programming logic and allow the developer to rapidly sort, group, and select data. Give your app a hypercard like capability.

Aggressive Rectangle Truncation (ART) with Location Verfication Mechanism is a localization algorithm in wireless sensor networks written in nesC.

Adaptive Simulated Annealing (ASA) is a C-language code that finds the best global fit of a nonlinear cost-function over a D-dimensional space. ASA has over 100 OPTIONS to provide robust tuning over many classes of nonlinear stochastic systems.

Este proyecto constituye una adaptacion y mejora del codigo ANFIS de dominio público de Roger Jang. / This project is an adaptation and improvement of the original public domain ANFIS code of Roger Jang.

Our aim is to create a collection of useful and free Ansi C libraries of code that are portable around systems.

The Arbitrarily-Decomposed MPI FFT library is a C subroutine library for the computation of the multidimensional Fast Fourier Transform (FFT) of a distributed grid using the Message-Passing Interface (MPI).

Aim is to develop a library of utility functions to efficiently simulate division, multiplication, mod, finding first 1/0 bit etc. (using shift and add/subtract) for software development on low cost dsp systems lacking these.

A C++ library for Bayesian computation, including a collection of more generally-applicable utilities.

Portable, optimised implementation of Bruce Schneier's 64-bit symmetric block cipher, Blowfish. Includes support for ECB, CBC, CFB, OFB and CTR block cipher modes, weak key detection and parallelisation using OpenMP.

BlueDS is a library that contains the implementation of frequently used data structures and algorithms in Computer Science. BlueDS is designed to be fast and efficient.

The Boehm-Demers-Weiser conservative garbage collector. The CVS source of the version 7+ collector resided here for a while, but is now on github. Other information and release snapshots are currently at http://hboehm.info/gc

The C Algorithms library has moved to GitHub. Please go to the new project page: https://github.com/fragglet/c-algorithms

Continuous wavelet transform library

A C++ library for clipping polygons.

A library of data structures with a unified API, written in portable C. Lists (uni- and bidirectional), a vector, a hash, a balanced tree (RB or AVL), a heap and tuples. Memory management, clone support, error handling.

CthughaNix is the reincarnation of Cthugha-L, a Linux port of one of the first audio visualization software packages, known as "An Oscilloscope On Acid".

An implementation of Dantzig-Wolfe decomposition built upon the GNU Linear Programming Kit. This is a command line tool for solving properly decomposed linear programs. There are several examples and some documentation to guide the use of this solver. Forked over to GitHub (see link).

Data Structure Tester is an OCaml application for multiple testing of various data structures (also written in other lanages, like C or C++).It proviedes many examples to test, easily configurable tester and signatures for all data structers to be tested.

From the early 1970s up to nowadays the system date routines of computers usually mix up date with time calculations. Not only that they will expire sooner or later due to number overflow. Not only that this will make calendarian calculations extremely complicated. Fact is, that this will combine two things together which don't have anything to do with each other: The rotation of the earth around itself and the rotation of the earth around the sun, which in addition will both vary during the chiliads. So how will you be able to do date calculations if you then even try to consider time gimmicks like summer/winter time changes, leap-seconds and so on? Just forget it! This project gives you very short pure date routines that are the fastest ones that you can get, because they don't need any looping for doing their calculations, and they do their calculations from 1/1/0 up to 12/31/9999. Of course they precisely consider the transition from Julian to Gregorian calendar. ;-)

Diagonal can be used for: - getting descriptive statistics such as mean/median/mode with your program producing a sample - finding a root of an equation your program defines - calculating a fixed point of a function your program defines - detecting a cycle of a fuction your program defines as well as - decoding a VCDIFF file

This is meant to be a powerful, but easy to use math software. It's by the user and for the users.

This is a general purpose expression evaluator which has abilities to evaluate mathematical expressions having operators: +, -, *, /, < , <=, >, >=, ==, !=, &&, ||. The enhancement to support all the other arithmetic operators is under development.

ExtraDix is a sorting algorithm based on Radixsort. It is faster than Quicksort, stable, realized in C and can sort by any basic data type. Testing was done with 1 million data records sorting char, short, int, long, float, double and strings.

FPM - Fixed Point Math substitutes expensive floating point operations by much cheaper integer arithmetics. Use this library in your plain C (gcc) projects if you like.

FastFlow is a C/C++ programming framework supporting the development of pattern-based parallel programs on multi/many-core, GPUs and distributed platforms. FastFlow run-time is built upon non-blocking threads and lock-free queues. Thanks to its very efficient CAS-free communication/synchronization support (e.g. few clock cycles core-to-core latency), FastFlow effectively supports the exploitation of fine grain parallelism, e.g. parallel codes managing very high frequency streams on commodity multi-core. FastFlow works on x86, x86_64, PPC, ARM, and Linux, Mac and Win XP/7. From Jan 1, 2018 code development migrated on GitHub at https://github.com/fastflow/fastflow
