popt4jlib is an open-source parallel optimization library for the Java programming language supporting both shared memory and distributed message passing models. Implements a number of meta-heuristic algorithms for Non-Linear Programming, including Genetic Algorithms, Differential Evolution, Evolutionary Algorithms, Simulated Annealing, Particle Swarm Optimization, Firefly Algorithm, Monte-Carlo Search, Local Search algorithms, Gradient-Descent-based algorithms, as well as some well-known...

An extension of the class javax.swing.JTree with a lot of improvements and utilities.

Arbaro is an implementation of the tree generating algorithm described in Jason Weber & Joseph Penn: Creation and Rendering of Realistic Trees

Stand-alone Java library implementing parser/formatter/comparator/validator for JSON/XML-like text formats oriented on JSON-like object model (list,map,scalar + reflection). Library is designed to maximize adaptivity via set of extendable modules.

Semantic query optimization (SQO) is the process of finding equivalent rewritings of an input query given constraints that hold in a database instance. We present a Chase & Backchase (C&B) algorithm strategy that generalizes and improves on well-known methods in the field. The implementation of our approach, the pegasus system, outperforms existing C&B systems an average by two orders of magnitude. This gain in performance is due to a combination of novel methods that lower the complexity in practical situations significantly.

The EURP OntoLookup is a CREOLE plugin for GATE http://www.gate.ac.uk/ which uses an OWL ontology for lookup. It has a very fast implementation based on a tree of hash maps.

Implementation of various mathematical curves that define themselves over a set of control points. The API is written in Java. The curves supported are: Bezier, B-Spline, Cardinal Spline, Catmull-Rom Spline, Lagrange, Natural Cubic Spline, and NURBS.
