VisualSort is a Java application for visualizing the way different sort algorithms work. Its implementation makes it easy to add new sort algorithms.

http://www.open-source-soft.narod.ru/VoiceDetector.7z It voice detector class,for detecting human speech, anti noise, anti tones, standard C++, completely cross-platform by recompilation.

**NOTE**: The WALA project is now hosted at https://github.com/wala/WALA; the latest source code and updates are available there. The code here on Sourceforge is highly out of date and unsupported. The T. J. Watson Libraries for Analysis (WALA) provide program analysis capabilities for Java bytecode and related languages. The WALA libraries constitute an open-source release of parts of IBM Research's DOMO analysis infrastructure.

Wallaroo is an infinite precision constraint solving and optimization library for linear constraints over the rational numbers. It handles equalities (=), inequalities (<=, >=), strict inequalities (<, >), and disequalities (!=).

Project consists in a software that reads a copied web site to your computer and generates a graph model of it. The model is based on the links, which are seen as the edges, and the pages, which are the vertices of the graph.

Weka++ is a collection of machine learning and data mining algorithm implementations ported from Weka (http://www.cs.waikato.ac.nz/ml/weka/) from Java to C++, with enhancements for usability as embedded components.

KNN-WEKA provides a implementation of the K-nearest neighbour algorithm for Weka. Weka is a collection of machine learning algorithms for data mining tasks. For more information on Weka, see http://www.cs.waikato.ac.nz/ml/weka/.

This is a GUI application for learning non disjoint groups based on Weka machine learning framework. It offers a variety of learning methods, based on k-means, able to produce overlapping clusters. The application also contains an evaluation framework that calculates several external validation measures. The application offers a visualization tool to discover overlapping groups.

This application talks to a GPS device over the NMEA protocol via the WIGSGPSComm API. The first version of the WIGS application will present the GPS data in an intuitive fashion, and later releases will be further enhanced with special map support.

Extract a Term Concept Map from Wikipedia. It takes an export of the Wikipedia and imports it into a database. The extracted term concept map can then serve as a basis for semantically enhancing applications, with the depth and bredth of the Wikipedia.

Simple platform independent library for comparing strings against the wildcard masks.

WordSort is an algoritm written in c# specifically designed for string sorting with linear complexity. Based on partial hashing approach, provides higher performance than classical algorithms that use the comparison. WordSort includes a console application easy and intuitive to use to evaluate and compare algorithms performance. Only Ordinal sorting and non-case-sensitive sorting provided.

X For You Feed Algorithm is the open-sourced core recommendation system that powers the For You feed on X (the social network formerly known as Twitter), and it represents one of the first times a major social platform has published production-level ranking code for public review and experimentation. The repository contains the full pipeline that ingests user engagement and content candidate data, processes it through retrieval, hydration, filtering, scoring, and selection layers, and ultimately ranks posts to show what appears in a user’s feed. At its heart, the system uses a transformer-based model adapted from xAI’s Grok architecture to predict probabilities for various user actions (such as likes, replies, reposts, clicks, and negative signals), then combines those into a weighted final score that drives ranking.

X-GAT (XML-based Genetic Algorithm Toolkit) is a Java framework to optimize problems with Genetic Algorithms (GAs). Differently from other frameworks, X-GAT contains ready-to-use GAs implementations and new features can be easily added.

XMLMath evaluates mathematical, logical or textual expressions described in xml and prints the result. For example, to compute the result of 1 + 1, you would write: <add> <long value="1"/> <long value="1"/> </add>

A simple PHP parser class that scans through poorly formed html documents as if they were valid XML, and generates calls to customizable callback functions.

XPN is relies on a non relational native XML database, where XML documents are stored in a compressed form and indices enables fast access to structure and content, thus enabling a fast evaluation of XQuery queries.

XanLib is a Linux library which provides data structures like hash tables, lists, pipes etc.. Each data structure exposes both synchronized and not synchronized methods.

A Java collections framework based on set theory, specifically, from Spivey's work on the Z notation (a formal specification language).

Lago is a study-oriented library of classic data structures and algorithms implemented in JavaScript with an emphasis on readability and learning. Instead of aiming to be a production runtime, it serves as a reference you can step through to understand how arrays, stacks, queues, linked lists, trees, heaps, graphs, and sorting/searching routines actually work. The implementations favor clarity over micro-optimizations, making them approachable for learners who are new to algorithmic thinking or coming from non-CS backgrounds. Because the code is idiomatic JavaScript, it also helps front-end engineers strengthen fundamentals without switching languages. The repository’s structure lets you browse topic by topic and compare trade-offs such as time versus space complexity. It’s a handy companion to interview prep lists: after reading a concept, you can open the matching Lago implementation and trace it line by line.

Yagnus attempts to provide you with useful software and libraries for more modern computing purposes.

Zero Sum Game Solver Java Library is open source java library to solve 2-player finite zero-sum games. This programs solve zero-sum games with linear programming.

Zero Sum Game Solver JavaScript Library

Zipline is a Pythonic algorithmic trading library. It is an event-driven system for backtesting. Zipline is currently used in production as the backtesting and live-trading engine powering Quantopian -- a free, community-centered, hosted platform for building and executing trading strategies. Quantopian also offers a fully managed service for professionals that includes Zipline, Alphalens, Pyfolio, FactSet data, and more. Installing Zipline is slightly more involved than the average Python package. For a development installation (used to develop Zipline itself), create and activate a virtualenv, then run the etc/dev-install script. Please note that Zipline is not a community-led project. Zipline is maintained by the Quantopian engineering team, and we are quite small and often busy.
