## Data description

This directory contains all datasets used in the numerical experiments.

### Numerical experiment 1: Quadratic optimization with exponential cone constraints

For each instance we provide the objective-function data files `P`, `q`, and `r` in the `data/Quadratic optimization with exponenial cone constraints` folder, representing `A_0`, `b_0`, and `c` respectively. Each data file contains the exact matrices/vectors/scalar used to generate the experimental results.

### Numerical experiment 2: Robust palatable diet problem

- The data for this numerical experiment is given in the folder `data/Robust palatable diet problem`. It contains three files:
  - `WFP_B_Matrix.csv`: This dataset is from [Maragno et al.](https://pubsonline.informs.org/doi/10.1287/opre.2021.0707) under the MIT license, retrieved from the [OptiCL Github repo](https://github.com/hwiberg/OptiCL/tree/main/notebooks/WFP/processed-data). It is used for calculating the objective palatability parameters.
  - `WFP_Costs.csv`: This dataset is from [de Moor et al.](https://www.sciencedirect.com/science/article/pii/S0377221724003333), retrieved from the associated [Zenodo archive](https://zenodo.org/records/8091487). It represents the costs parameters `c_k`. This data was obtained July 01, 2023.
  - `WFP_dataset.csv`. This dataset is from [Peters et al.](https://pubsonline.informs.org/doi/10.1287/inte.2021.1097), also available on [Zenodo archive](https://zenodo.org/records/8091487). It represents the nutrient coefficient values `beta_kl`. This data was obtained July 01, 2023.
