GA-EoC
GeneticAlgorithm-based search for Heterogeneous Ensemble Combinations
...To enhance classification performances, we propose an ensemble of classifiers that combine the classification outputs of base classifiers using the simplest and largely used majority voting approach. Instead of creating the ensemble using all base classifiers, we have implemented a genetic algorithm (GA) to search for the best combination from heterogeneous base classifiers. The classification performances achieved by the proposed method method on the chosen datasets are promising. -

DE-HEoC
DE-based Weight Optimisation for Heterogeneous Ensemble
We propose the use of Differential Evolution algorithm for the weight adjustment of base classifiers used in weighted voting heterogeneous ensemble of classifier. Average Matthews Correlation Coefficient (MCC) score, calculated over 10-fold cross-validation, has been used as the measure of quality of an ensemble. DE/rand/1/bin algorithm has been utilised to maximize the average MCC score calculated using 10-fold cross-validation on training dataset. -

jPass - Cross-Platform Password Manager
Compiled into a single .jar file. Tiny Password Manager. Portable
I did not see a pre-built version of this software on the original developers Github project (https://github.com/gaborbata/jpass), so I am taking it upon myself to compile the releases as they come, so that others don't have to. --Description-- JPass is a simple, small, portable password manager application with strong encryption. It allows you to store user names, passwords, URLs and generic notes in an encrypted file protected by one master password. I will not add the source... -

sWangTiler
A java implementation that generates wang tiles from any input image.
...Wang tiles greatly reduce visible repetitions making textures seem more natural and thus improve the quality of any graphic application like games, simulations etc. This implementation is based on the strict wang tile algorithm as proposed by Xinyu Zhang and Young J. Kim in "Efficient Texture Synthesis Using Strict Wang Tiles". In order to calculate the lowest cost path between any edge- and sample image an implementation of Dijkstra's algorithm is used which was found in the java graph library 'JGraphT'. Credits to all mentioned parties and to http://www.texturemate.com/. -

Generate complex SNP models and heterogeneous datasets
Genetic Architecture Model Emulator for Testing and Evaluating Software (GAMETES) is an algorithm for the generation of complex single nucleotide polymorphism (SNP) models for simulated association studies. GAMETES is designed to generate epistatic models which we refer to as pure and strict, that constitute the worst-case in terms of detecting disease associations, since such associations may only be observed if all n-loci are included in the disease model. -
