A cross-platform library that computes fast and accurate SIFT image features. libsiftfast provides Octave/Matlab scripts, a command line interface, and a python interface (siftfastpy). Optimized with SIMD instructions and OpenMP .

Significant gains in processing times when sorting arrays with structure in the data. Pre-sorted arrays with relatively few modifications may be sorted 20-30 times faster than Delphi's default QuickSort. The project includes a test suite.

Libraries providing optimized alternative implementations for Delphi VCL/RTL functions, methods and classes.

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

This is showcase program, with source code and sample data included for fast peak detection algorithm. It is great tool for entry level, automated analisys, to discard empty and junk curves and save only ones matching required criteria. Assuming that only 1% of data is worth reviewing, and that manual selection takes approx. 3 seconds per curve, you can save up to 8 hours per every 10000 curves (like 2 days every week!). Force amplitude analisys for single curve takes from 1 to 4 milliseconds on low-end intel dual core. Algorithm is so simple, that you can implement it in any language in few hours, without any specialized libraries. To be implemented in our Nanopuller AFM control software as real-time module. Requires LabVIEW Runtime engine to run .exe or LabVIEW 2013 for code.

This is a tidy lightweight library implementing a series of C++ Design Patterns, aiming to be simple, clean and portable. This library is made to help C++ programmers to develop projects with clearer and more compact source code.

A unified collection of ruby data structure and algorithm packages.

This library is available on GitHub: https://github.com/ronflima/feijuca Get it from there.

java library for heuristic optimization algorithms.

This project is open source program and finding minimum cost of daily menu.

A C library, providing comfortable APIs for a wide range of Finite State Abstract Machines (NFA, DFA, FST, Bimachines, etc). Implements most of the classical algorithms in the field.

Fiona is a tool to automatically analyze the interactional behavior of a given oWFN. It provides two techniques: it checks for the controllability of the given net by computing the interactiong graph and it calculates the operating guideline for the net.

LZO is a compression library which is widely used around the world. The main problem with LZO is that it is absolutely not human readable. People have done crazy stuff to get LZO to run in their language. Usually it implies inline assembly or trying to execute data which actually contains machine code. This is sick. Whoever is responsible for this sorry situation ought to be ashamed. So I'm going to deobfuscate LZO and provide a ISC implementation of this algorithm in Python and C. In addition, I will provide a textual description of the algorithm so that it can be easily ported to any programming language. I expect a severe performance degradation, but I leave optimizing for speed to other people.

A really fast static spatial index for 2D points and rectangles in JavaScript. An efficient implementation of the packed Hilbert R-tree algorithm. Enables fast spatial queries on a very large number of objects (e.g. millions), which is very useful in maps, data visualizations and computational geometry algorithms.

This is a python implementation that handles floating points correctly,there are still some bugs but I'm working on it . The point was to work around some stuff that made no sense for floats,like 0.1+0.2 == 0.3 is false.

A project to prevent spam and trackback-links in your guestbook and comments.

FORce based Cluster Editing (FORCE) is a Java software heuristically solving the graph cluster editing problem on weighted edges using BLAST E-values. It further provides a training mode for heuristic parameter estimation.

A p2p filesharing application, where every1 is forced to seed for a certain period and then every1 gets to download with a guaranteed number of seeders as well, for a certain perion of time.
