Jafama (Java Fast Math) consists of fast - but not sloppy - counterparts of java.lang.Math treatments, plus additional ones. They are usually about 2-4 (up to 15) times faster, with about 1e-15 accuracy, and handle special cases (NaN, etc.). Since version 2.1, a StrictFastMath class is also provided. It is a strictfp version of FastMath (and not a fast version of StrictMath): for a same version of this library, its methods always return a same result for same arguments, which might not be the case for FastMath depending on JIT or other JVM optimizations. Requires Java 5 or later. Available on Central since 2015/06/05. Also available on github since 2015/12/13: https://github.com/jeffhain/jafama

It's a program that plots Bode diagrams with an excellent precision. In this new version it's very easy to provide the function to plot thanks to a simply graphic interface in style "what you see is what you got". A smart output window allows to plot more than one graph at the same time, and easily compare them. The plotted graphs can be exported as images, in various format. Language supported: italian. Next version probably will include other languages; certainly english will be the first. This is a beta version, so please report any bug if you find something wrong! Your help will be very appreciated! NEWS! asymptotic diagram plotting function added! the function is in beta test, and does not support complex factor.

Nebular is a fuzzy logic API written in Java. It is written in pure Java and comprehends fuzzy logic, fuzzy sets and operations, fuzzy control, decision support, type 2 fuzzy logic and type 2 fuzzy intervals.

A Java package that provides routines for various statistical distributions. Based on R version 2.14.1 (continuously updated; current as of R v3.3.0). The major difference is that JDistlib is thread safe. The library contains the density (pdf), cumulative (cdf), quantile, and random number generator (RNG) routines of the following distributions: Ansari, Beta, Binomial, Cauchy, Chi square, Exponential, Fisher's F, Gamma, Geometric, Hypergeometric, Kendall, Logistic, Log normal, Negative binomial, Noncentral beta, Noncentral chi square, Noncentral f, Noncentral t, Normal, Poisson, Sign Rank, Spearman, Student's T, Tukey, Uniform, Weibull, Wilcoxon, and many more. Normality tests, such as: Kolmogorov-Smirnov, Anderson-Darling, Cramer-Von Mises, D'Agostino-Pearson, Jarque Bera, Kolmogorov-Lilliefors, Shapiro-Francia, Shapiro-Wilk. And many others.

Perceptron is a video feedback engine with a variety of extraordinary graphical effects. Perceptron is an endless flow of transforming visuals. Perceptron * recursively transforms images and video streams in realtime and produces a combination of Julia fractals, IFS fractals, and chaotic patterns due to video feedback * evolves geometric patterns into the realm of infinite details and deepens the thought * records animations (movies) * saves and opens presets (state files) * loads user photographs or captures screen and webcam input * has user interface based on multiple mouse cursors, and almost the entire keyboard * has multiple windows and fullscreen mode * takes complex geometric transforms as input * applies numerous coloring techniques * smoothly transforms fractals and creates endless psychedelic journeys * resonates with the human perception Visit the Perceptron home page at http://perceptron.sourceforge.net

Automatous Monk is a Java application that maps cellular automaton evolutions into music. The resulting music is represented as jMusic scores that can be played and saved as MIDI files. A real-time version, which uses JSyn, is also available.

A cross-platform, text-interpreting calculator written in the Java programming language. Runs on any computer with Java 6 or higher installed. Functions much like a Ti-84, but without the graphing utility.

A Java application enabling users to create, edit, and view sports or competition results. In addition, there are facilities to view league tables and other statistical information based on the results.

Opt4J is an open source Java-based framework for evolutionary computation. It contains a set of (multi-objective) optimization algorithms such as evolutionary algorithms (including SPEA2 and NSGA2), differential evolution, particle swarm optimization, and simulated annealing. The benchmarks that are included comprise ZDT, DTLZ, WFG, and the knapsack problem. The goal of Opt4J is to simplify the evolutionary optimization of user-defined problems as well as the implementation of arbitrary meta-heuristic optimization algorithms. For this purpose, Opt4J relies on a module-based implementation and offers a graphical user interface for the configuration as well as a visualization of the optimization process.
