Minion is a high-performance derivative-free optimization library designed for solving complex optimization problems where gradients are unavailable or unreliable. It implements state-of-the-art evolutionary algorithms, including top-performing methods from IEEE CEC competitions, which are often missing in standard optimization libraries such as SciPy, NLopt, OptimLib, pyGMO, and pagmo2.Minion is not only a solver but also a research platform for developing and testing new optimization algorithms [...]

Massive-Parallel Trajectory Calculations (MPTRAC) is a Lagrangian particle dispersion model for the analysis of atmospheric transport processes in the free troposphere and stratosphere. This repository hosts MPTRAC version 3.0, as described in: Hoffmann et al. [...]

The Metadata Archivist is a simple framework to process multiple heterogenous input files and unify the parsed information into a singular structured output. Users must define their own parsing procedures, then with a convenience class offered by our framework, orchestrate exploration the exploration of a given directory or archive, filtering of files to process, parse and optionally structure the target, lastly export the output to a selected format..

This archive contains an example implementation of a knowledge generation workflow. Here the questions to answer relate to benchmarking and validation of a given simulator and model. [...]

Christmas release! ChASE can now tackle pseudo-Hermitian problem as they arise, for instance in Bethe-Salpeter equation. The solve has been extended by generalizing the Chebyshev filter and designing a new oblique method for the Rayleigh-Ritz projection. [...]
