✅ FAIR COMPARISON ANALYSIS (n-1 edges)
================================================================================

Edge Count: n-1 = 29 edges

1. Kruskal (Optimal): 1177.43
2. ACO TSP Path:      1995.57
3. ACO MST:           1177.63

Gap from Optimal:
  TSP Path vs Kruskal: +69.48%
  MST vs Kruskal:      +0.02%

✅ Fair comparison karena:
  • Same edge count: 29 edges
  • No cycle: TSP Path & MST both are paths/trees
  • Apple-to-apple: Both connect all nodes without cycle

💡 KEY FINDINGS:
  • All methods use n-1 = 29 edges (FAIR!)
  • TSP Path: NO cycle (like MST)
  • Kruskal: 1177.43 (optimal)
  • ACO TSP Path: 1995.57 (+69.48%)
  • ACO MST: 1177.63 (+0.02%)
