Pre-requirements

1. Please install MATLAB application.
2. Please install and follow the procedure from the GreenLight as it's the main core program for the physics based model.
3. Please install RLlib .whl from this repositoryin the Installling Ray folder. Follow this link to install it Installing Ray.

Using the model

1. Please follow the "Using the model" procedure from the original this link GreenLight. Do not forget to install the appropriate pre-requirements, for example the MATLAB version and DyMoMa package. Furthermore, do not forget to set path of the folders appropriately.
2. After it can run the example model of the original GreenLight. Try to run the exampleMiniGreenhouse in this repository mini-greenhouse-greenlight-model. The .mat file is inside the Code/runScenarios/exampleMiniGreenhouse.m. In here, it can run the example based on the parameters for the mini-greenhouse. This folders also need in the MATLAB path.
3. After step 1 and 2, run the main-run-offline.py in this repository mini-greenhouse-model, and do not forget to set path for the MATLAB folder to the MATLAB application. In here the application can run the DNN and LSTM models. In addition, with main-run.py can run the DRL model.
