EvoLib Version 2.1.0 - 10/26/2019

EvoLib is an open source implementation of NSGA-II, NSGA-III and Unified NSGA-III (U-NSGA-III). NSGA-II is a well known Evolutionary Multiobjective Optimization (EMO) algorithm than can handle up to two objectives efficiently. NSGA-III is a widely used algorithm for handling multi (2, 3) and many (3 to 20) objectives. However, NSGA-III was shown to be less efficient with single objective optimization problems. U-NSGA-III is an improved version of NSGA-III that enhances the performance of the original algorithm in single objective optimization problems while maintaining its high performance in multi and many objective optimization problems.

DEPENDENCIES

  1. Tx2Ex: An open source mathematical expressions parser (Apache L2 License)
  2. Apache Commons Lang3 (Apache L2 License)

  5. Generate detailed Matlab plotting script
  6. Easily extensible pure object oriented design
  7. Detailed comments provided with source code

GETTING STARTED

To modify EvoLib directly, clone it to your local file system using Git, then have fun. A good start point is to run optimization.SampleScript (a sample script for optimization problems involving only real-valued variables). If you want to use EvoLib in your own project as a dependency, the recommended approach is to install your local clone of EvoLib into your local Maven repository and use it from wherever as a Maven dependency. The latter approach is usually the case if your problem involves custom variables and consequently needs custom operators. For a detailed example on how to setup and develop such projects, take a look at EvoLib-Demo (https://github.com/000haitham000/evolib-demo)
