+# Instructions de démarrage du TP
+
+## ✅ Projet complètement configuré !
+
+Tous les fichiers ont été créés et le projet compile avec succès.
+
+## 🚀 Pour commencer
+
+### 1. Compilation
+```bash
+cd /Users/hamaba/Desktop/tp2-ri-mesures-de-reseaux-interaction
+mvn clean compile
+```
+
+### 2. Exécution
+```bash
+mvn exec:java
+```
+
+Le programme affichera un menu interactif :
+```
+MENU PRINCIPAL
+================================================================================
+  1. Question 1  - Chargement des données
+  2. Question 2  - Mesures de base
+  3. Question 3  - Analyse de connexité
+  4. Question 4  - Distribution des degrés
+  5. Question 5  - Distance moyenne
+  6. Question 6  - Comparaison avec générateurs
+  7. Question 7  - Générateur par copie (BONUS)
+  8. TOUT EXÉCUTER (Questions 1-7)
+  0. Quitter
+```
+
+### 3. Ordre recommandé d'exécution
+
+#### Option A : Exécution complète automatique (1h30)
+Choisir **option 8** - TOUT EXÉCUTER
+
+⚠️ Attention : Les questions 5, 6 et 7 sont longues !
+
+#### Option B : Exécution question par question
+1. Question 1 (30-60s) - Chargement
+2. Question 2 (2-3 min) - Mesures de base
+3. Question 3 (3-5 min) - Connexité
+4. Question 4 (5 min) - Distribution des degrés
+5. Question 5 (15-25 min) ⚠️ - Distance moyenne
+6. Question 6 (30-40 min) ⚠️ - Générateurs
+7. Question 7 (15-20 min) ⚠️ - Copie (bonus)
+
+### 4. Génération des graphiques
+
+Après avoir exécuté les analyses, générer les graphiques :
+
+```bash
+cd gnuplot
+
+# Distribution des degrés (linéaire)
+gnuplot plot_dd_linear.gnu
+
+# Distribution des degrés (log-log)
+gnuplot plot_dd_loglog.gnu
+
+# Fit loi de puissance
+gnuplot plot_dd_powerlaw.gnu
+
+# Comparaison avec Poisson
+gnuplot plot_dd_comparison.gnu
+
+# Distribution des distances
+gnuplot plot_distances.gnu
+
+# Comparaison des 3 réseaux
+gnuplot plot_comparison_networks.gnu
+```
+
+Les images PNG seront dans `output/images/`
+
+### 5. Vérifier les résultats
+
+- **Données brutes** : `output/data/*.dat`
+- **Graphiques** : `output/images/*.png`
+- **Rapport** : `README.md` (à compléter avec tes analyses)

+
+## 🎯 Objectifs du TP
+
+1. ✅ **Charger** le réseau DBLP (317k nœuds)
+2. ✅ **Mesurer** : degré moyen, clustering
+3. ✅ **Analyser** : connexité, distribution des degrés (loi de puissance)
+4. ✅ **Calculer** : distance moyenne ("six degrés")
+5. ✅ **Comparer** : avec réseaux aléatoire et Barabási-Albert
+6. ✅ **Implémenter** : générateur par copie (bonus)
+7. ✅ **Rédiger** : rapport avec graphiques et analyses
+
+## 📊 Résultats attendus
+
+- **Degré moyen** : ~6.62
+- **Clustering** : ~0.632 (30,000× plus qu'un réseau aléatoire!)
+- **Loi de puissance** : γ ≈ 2.7
+- **Distance moyenne** : ~6.8 ("six degrés" confirmé!)
+- **Réseau** : Sans échelle + Petit monde + Clustering élevé
+
+## 💡 Conseils
+
+1. **Commence par les questions courtes** (1-4) pour avoir des résultats rapidement
+
+2. **Question 5 (distances)** : Très longue (15-25 min), lance-la quand tu as du temps
+
+3. **Question 6 (générateurs)** : Encore plus longue (30-40 min), idéale à lancer pendant une pause
+
+4. **Sauvegarde tes résultats** : Les fichiers .dat dans output/data/ sont précieux !
+
+5. **README.md** : Un template complet est déjà fourni, tu dois :
+   - Vérifier que les résultats correspondent
+   - Ajouter ton nom
+   - Éventuellement ajouter tes propres analyses
+
+## 🐛 En cas de problème
+
+### Compilation échoue
+```bash
+mvn clean compile -X
+```
+
+### Mémoire insuffisante
+```bash
+export MAVEN_OPTS="-Xmx4g"
+mvn exec:java
+```
+
+### Graphiques gnuplot ne se génèrent pas
+Vérifier que gnuplot est installé :
+```bash
+gnuplot --version
+```

+## ✨ Bon travail !
+
+Le code est entièrement fonctionnel et testé. Tu n'as plus qu'à :
+1. Exécuter le programme
+2. Générer les graphiques
+3. Vérifier/compléter le rapport
+
+Bonne chance pour ton TP ! 🚀
