Ceci est le répertoire Git du projet d'optimisation métaheuristique du groupe 9 dont les membres sont **AIT MOUSSA Amine, DAANOUNI Siham et DELAMOTTE Clément**.
|
||||
|
||||
Le sujet choisi est **l'optimisation du chargement des véhicules électriques** et l'algorithme mis en place est **Multiple Objectives Particle Swarm Optimization (MOPSO) + Surrogate**. La modélisation du problème se trouvera dans le rapport.

Pour les datasets, nous avons pris diverses sources pour concevoir notre propre jeu de données:
|
||||
- data/vehicle_capacity.csv: [Car Dataset (2025)](https://www.kaggle.com/datasets/abdulmalik1518/cars-datasets-2025/data)
|
||||
- data/elec_prices.csv: [RTE France (éco2mix)](https://www.rte-france.com/donnees-publications/eco2mix-donnees-temps-reel/donnees-marche), les données ont été récupérées manuellement sur l'hivers 2025 (S2-S5) et l'été 2025 (S29-S32)

## Installation
|
||||
Le projet a été concu à l'aide du *Python packet manager* ***UV***, il est préférable d'utiliser celui-ci pour ca facilité d'utilisation. **UV** peut être installé via le [site internet officiel](https://docs.astral.sh/uv/getting-started/installation/#installing-uv).
|
||||
Pour télécharger le projet vous pouvez simplement utiliser la commande `git clone https://gitea.galaxynoliro.fr/KuMiShi/Optim_Metaheuristique.git` ou récupérer le fichier `.zip` du projet et l'extraire.
