This library implements PEG (Parsing Expression Grammar) parsers, which can be embedded in a C++ program. The grammars are built and interpreted at run time, without an intermediate code generation stage. It tries to mimic as closely as possible the functionality and style of Ian Piumarta's LEG compiler. LEG grammars can be translated easily and almost mechanically. Actions and semantic predicates can be written directly in the grammar, using lambdas. C++11 or later is required.

Framework: Project for Evolutionary Predator Prey Algorithms, used to implement an evolutionary scheme based on the developement by van Laumanns. Implement testproblems, special behaviours, environments, and other yet not known features.

phonet4j is the port of a extensible, rule based algortihm for phonetic conversions written by Joerg Michael to java. His code was first published in the computer magazine c't (issue 25/1999, pp. 252). Includes two rulesets for the german language.

phonet4n is an extensible phonetic string conversion algorithm. It is a .net implementation of a powerful German phonetic library described in "doppelgaenger gesucht", c't 25/99, p. 252.

A PHP library to generate and verify Italian national identification number. Una libreria PHP per calcolare e verificare la validità di codici fiscali.

Phpf2f (php4 to 5) is a shell script written by Mariano Fiorentino, to migrate php4 code into php5 syntax.

plausj a collection of checksum algorithms used to validate business keys like bank account codes or credit card numbers. It's compiled as JVM bytecode files (although it's not necessarily implemented in Java) and can be used on JRE 1.5 and later.

General purpose state observation library for Plan Old Java Objects. It enforces Model-View-Controller paradigm, has well defined API and set of ready made implementation algorithms.

This is a Su-do-ku game solver and player. It generates a complete Sudoku.

pun - A library for numerical analysis and statistics.

Using Chinese description. You need the Google translation. My address is as follows: No.17-18 of XiangGang batang Community, Xiangtan City of Hunan Province, China.

pyMVC is a Model-View-Controller implementation library and framework written in Python for fast and high-grade software development.

A generic purpose library in Python. It includes directed graphs, dependency graphs, threads-related algorithms, etc.

Store your pieces of code and search it quickly

The aim of the project is to provide reference implementations of data structures along with supporting references to publications and other materials. The only purpose is for fun and education: I like data structures.

Python library for a fast and flexible graph data structure.

pyhanlp is a Python interface for HanLP (Han Language Processing) that lets you use a mature Java-based NLP toolkit from Python workflows without rebuilding the underlying algorithms. It is commonly used for Chinese-language NLP tasks where you want production-grade tokenization and linguistic analysis, but still want the convenience of Python scripting. The project focuses on making HanLP’s capabilities accessible through a Python-friendly API surface, so you can integrate NLP steps into data pipelines, notebooks, and downstream ML or information-extraction code. In practice, it serves as a bridge layer: Python calls are translated into the corresponding HanLP operations, so you can keep your application logic in Python while relying on HanLP’s implementations. It is especially useful when you need a pragmatic “get results quickly” NLP layer for segmentation, tagging, entity extraction, parsing, or keyword-style tasks rather than experimenting with model training from scratch.

pythag is an algorithm and script for computing primitive Pythagorean triples using the command line. Has an option to output to a file. It also has an option to output to a graph using GLUT, to which it now depends.

ngram is a module to compute the similarity between two strings. It is different to python's "difflib.SequenceMatcher" in that it cares more about the size of both strings. ngram is an port and extension of the perl module called "String::Trigram

small QT Programm for Testing my recursive Algorithm for calculation the bitreverse of a single number in a series with Length: 2^X with X=Number of Bits

quadGT is a software package for the joint genotyping of two parents, child’s normal genome and child’s tumor genome based on sequencing reads aligned to a reference genome.

Sample code, algos, what you got?

Alternative approach to minimum redundancy coding (fixed-length) without using tree data structures. The main advantages are simplicity and flexibility.

It software decodes EAN-13 bar code picture by image processing. And a GUI is ship together with it, which can take picture from web camera. So the only thing you need to recognise barcode apart you computer is a webcam.
