Cul is a simple utility library written in c programming language that provides many typical structures (vectors, matrices, lists, trees) and algorithms (automatic structure management, sorting, etc.) for the programmer.

Simple and Fast Exception Handling for C.

CGL(C Generic Library) is a stl-like library written in pure C.It implements iterators, memory management,generic containers such as list,map, generic algorithms such as sort() and search(),and it can manipulate any types of data.

CRCLIB is a small library of CRC calculations which can be used in other programs. Because CRC check is often used by binary communication protocols, it is made as simple as it can be, built into library so that it could be used regardless of language of application code. Written in plain C, built as dll and static library, and also contains C/C++ import header, C# wrapper and .NET project for MS SQL Server assembly. Supports CRC16 (including MODBUS) and CRC32.

A capsule tree is a general purpose, self-balancing tree data structure for large, ordered, data-sets. It is designed to provide the same characteristics as B-trees and B+trees, but built from the ground up for in-memory usage. In other words, there are no provisions for “slow” I/O cases. The original motivation for this tree was a better backend for memory managers. However, the end result was a new sub-category of trees. The implementation giving here is just one implementation of the new tree sub-category, there can be others. In any case, read the PDF: “Capsule Trees - A Primer”, before delving into the code.

Given a placement of pieces on a chessboard, find the move which forces checkmate as rapidly as possible.

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.

Project provides a set of concurrent building blocks (Java & C/C++) that can be used to develop parallel/multi-threaded applications. Components are grouped into 4 categories: 1.Data Structures 2. Parallel Patterns 3.Parallel functions 4.Atomics and STM

Modified NCBI Toolkit for Windows, added contextual BLAST algorithm.

Crazy Turtle puzzle game solver utility. Other names: CRAZY TURTLE / LE JEU FOU DE LA TORTUE / NAUGHTY TURTLES / ŠAŠAVE KORNJAČE / NAGAJIVE ŽELVICE / SASAVE KORNJACE

Cryptography Tools is a project to develop demonstration tools on classic (currently Caesar and Playfair) & modern crypto-systems, including private & public key encryptions, digital signatures, cryptographic hashes and authenticated encryption.

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".

With this application you can know all, about current time! Day, month, year, Week day, clock (hours, minutes and seconds), time of execution of application (years, months, weeks, days, hours, minutes and seconds). -> This application has a miniscule consumption of resources. -> This application doesn't need any configuration just need to be executed.

D-List is an extensive, production quality, and robust list management subsystem written in C that can be used as a shared library or compiled directly into your project. D-List provides access to 3 classes of lists, and allows extensive manipulation and customization of these lists. D-List lists can also be easily incorporated as primitives into larger treed, or nested data management systems. D-List implements a comprehensive set of linked list primitives that provides multiple forms of both sequential and random element access, bi-directional movement within a list, and an extensive set of list and element manipulation and reordering features. It also provides for an expansive set of user functions that can be added to lists and called automatically, to efficiently implement a broad range of services using the list primitives as underlying technology. It was written primarily for accuracy and speed, and provides extensive debugging support for easy code development.

DDMTestbed is a testbed that allows you to generate random instances and evaluate your proposed resolutive method measuring execution time, memory occupied and distance from the optimal solution. It has been written in C language.

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

We introduce our implementation that accelerates the distance matrix computation in the x86 and Cell Broadband Engine (BE) architecture, a homogeneous and heterogeneous multi-core system, respectively.

DMTA (Distributed Multithreaded Apriori) is a parallel implementation of Apriori algorithm, which exploits the parallelism at the level of threads and processes, seeking to perform load balancing among the cores. Was implemented in C++ language, using the parallelization libraries OpenMP and MPI. The algorithm was generated as a result of a project developed by André Camilo Bolina, under the guidance of teachers Marluce Rodrigues Pereira, Ahmed Ali Abdalla Esmin and Denilson Alves Pereira, in Department of Computer Science at Federal University of Lavras. The results of this project were published in the Revista de Sistemas de Informação da FSMA and is available in http://www.fsma.edu.br/si/edicao11/FSMA_SI_2013_1_Principal_1.html

Evolutionary Structural Optimization Package (ESOP) consists of software for viewing, analyzing, and optimizing structures containing beam, truss, and membrane plate elements utilizing OpenGL and the Genetic Algorithm (GA). Created for use in M.S. theses

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

Ertha is an open source GIS whose main focus is to guarantee easy extensibility and straightforward integration of custom modules. It provides basic geographic rendering and topologic analysis and exposes the main data structures loaded from shapefiles.

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.
