An OpenSource Least-Squares-Adjustment Tool
JAG3D is no longer developed at source-forge, and has moved to GitHub. Please visit https://github.com/loesler/applied-geodesy JAG3D is a simple tool to estimate geodetic 1d, 2d and 3d-networks by a least-squares-adjustment called Gauß-Markov model. For gross-error detection, the software supports common outliers tests (based on hypothesis testing) and robust L1 norm (BIBER estimator). Moreover, the software supports deformation-analysis on the observation level. This network adjustment application supports classic observations: - Distances 2D/3D, - Directions and/or azimuths, - Zenith angles, - Levelling difference as well as - GNSS-baselines 1D, 2D and 3D. Further feature (add-ons): - Coordinate-transformation (CoordTrans), - Form analyser (FormFittingToolbox), - Datum-transformation (UTM, Gauß-Krüger, Soldner; WGS84, Bessel, Krassowski, Hayford; NTv2 ...)
Modular Java framework for meta-heuristic optimization
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.

jChecs is an open source Java chess program, designed to introduce the basics of computer chess programming concepts.
The source code has been migrated and is now hosted on Github: https://github.com/jenetics/jenetics Jenetics is an advanced Genetic Algorithm, Evolutionary Algorithm and Genetic Programming library, respectively, written in modern day Java. It is designed with a clear separation of the several algorithm concepts, e. g. Gene, Chromosome, Genotype, Phenotype, Population and fitness Function. Jenetics allows you to minimize or maximize the given fitness function without tweaking it. In contrast to other GA implementations, the library uses the concept of an evolution stream (EvolutionStream) for executing the evolution steps. Since the EvolutionStream implements the Java Stream interface, it works smoothly with the rest of the Java Stream API.
