-#### Highlights:
+<img src="./assets/MOO4Modelica_framework.png" alt="framework" style="zoom:80%;" />
 
-1. **Easy to configure:** All configurations can be defined in `config.json`.
-2. **SoTA algorithms:** Dynamic import of algorithms from *pymoo*.
-3. **Enable use of** **parallel computing**: For accelerated process. 
-5. **Support transformation into feature models**: To better analyze and understand large-scale models.

-* (Feature Model Transformation)
+* **Feature Model Transformation**
   * `modelica.g4`: an ANTLR4 grammar for Modelica files
   * `parse_modelica.py`: parse a Modelica model to extract it components and their parameters
   * `feature_model.py`: create a feature model and add the extracted components
-* (Optimization Operation)
+* **Optimization Operation**
   * `config.json` & `config.py`: global settings and configurations
   * `optimize_main.py`: main optimization script
   * `parallel_computing.py`: parallel computing
   * `optimization_libraries.py`: dynamic import of algorithms from *pymoo*
