 ```PyPop7``` is a *Pure-PYthon* open-source library of **POPulation-based OPtimization** for single-objective, real-parameter, black-box problems (*currently actively maintained*). Its goal is to provide a *unified* interface and a set of *elegant* algorithmic implementations (e.g., evolutionary algorithms, swarm-based optimizers, pattern search, etc.) for **Black-Box Optimization (BBO)**, *particularly population-based optimizers*, in order to facilitate research repeatability, benchmarking of BBO, and especially real-world applications.

 More specifically, for alleviating their **curse of dimensionality**, the focus of ```PyPop7``` is to cover their **State Of The Art for Large-Scale Optimization (LSO)**, though many of their small/medium-scaled versions and variants are also included here (mainly for theoretical or benchmarking or educational purposes). For a list of **public use cases** of `PyPop7`, please refer to [this online document](https://pypop.readthedocs.io/en/latest/applications.html) for details. Although we have chosen *GPL-3.0 license*, anyone could use, modify, and improve this open-source Python library **entirely freely** for any (no matter open-source or closed-source) purpose.
