Stop Storing Third-Party Tokens in Your Database
Auth0 Token Vault handles secure token storage, exchange, and refresh for external providers so you don't have to build it yourself.
Rolling your own OAuth token storage can be a security liability. Token Vault securely stores access and refresh tokens from federated providers and handles exchange and renewal automatically. Connected accounts, refresh exchange, and privileged worker flows included.
Hypergherkin is a library for the manipulation of Real valued algebra expressions including equation simplification, symbolic integrals & derivatives. Workings can be rendered using the default presentation MathML generator or a custom alternative
Triple-A (Automatic Analysis with Automata) is a full-featured library for (finite) automata written in Java with two powerful analysis tools (dealing with LTL model checking and Presburger arithmetics) and a graphical user interface built around it.
The Simple Interface for Global Optimization Algorithms allows the specification of arbitrary search/optimization problems, solving of these problems, and the specification and implementation of optimization algorithms like evolutionary algorithms.

JMatrixCalc is a Java package used for matrix calculations. It's aim is to make developing many scientific (and non-scientific as well) project much easier and quicker. These projects include: educational software, statistics and many others.
A full math Java class library containing complex functions and algorithms such as cubic-spline interpolation, least squares, matrix computations. Eventually to make a web based interface to the library using JSP.
The project is about turn-based, networked multiplayer, non-cooperative, zero-sum, abstract strategy board games (e.g. Chess, Go, Reversi variants, etc.) on 3D-visualized polyhedra and related recreational (discrete, computational) mathematics.
The project Formula can be used for the computation of numeric expressions that is written as string. Main features of the project are high computation speed and simplicity of use. Formula can be used for writing of calculators, plotters and etc.
XCalc is an infix calculator for mobile devices that support J2ME, MIDP 1.0 and CLDC 1.0.Its main features are 2d and 3d plotting of functions and its usability. It uses the Real.java library http://sourceforge.net/projects/real-java.

{sets} is a lightweight constraint programming language. The uniqueness of {sets}, is that it uses ROBDD ( Reduced Ordered Binary Decision Diagrams ) to represent and solve constraints.
Java Kohonen Neural Network Library
Kohonen neural network library is a set of classes and functions for design, train and use Kohonen network (self organizing map).
John has between 2 and 5 apples. Mary gives him between 3 and 7 apples. How many apples does he have now? If you even understand this question, you understand interval arithmetic. This Javalibrary implements interval arithmetic for all operators.
The K.U.Leuven JCHR System is an integration of Constraint Handling Rules (CHR) and Java designed with three aims in mind: user-friendliness, flexibility and efficiency.
