================================================================================
BEE COLONY OPTIMIZATION (BCO) FOR MST PROBLEM
================================================================================
PERBEDAAN UTAMA BCO vs ACO:
ACO (Ant Colony Optimization):
- Ants: ALL construct solutions independently
- Pheromone: Updated AFTER all ants finish
- Communication: INDIRECT (via pheromone trails)
- Selection: Probabilistic based on pheromone + heuristic
BCO (Bee Colony Optimization):
- Bees: THREE types with different roles
1. SCOUT BEES: Explore random solutions
2. EMPLOYED BEES: Exploit known good solutions
3. ONLOOKER BEES: Choose best solutions to refine
- Communication: DIRECT (waggle dance - sharing solutions)
- Selection: Tournament selection + probabilistic
- Memory: Best solutions stored in "hive memory"
KEY DIFFERENCES:
1. **ROLE DIFFERENTIATION**: BCO has scout/employed/onlooker roles
2. **WAGGLE DANCE**: Bees share solution quality directly
3. **ABANDONMENT**: Poor solutions abandoned after limit tries
4. **NEIGHBORHOOD SEARCH**: Local search around good solutions

PERFORMANCE SUMMARY
ACO (Ant Colony Optimization):
- Best for: Simple unconstrained MST
- Gap: 0.09% (very close to optimal!)
- Strength: Stability, simplicity
BCO (Bee Colony Optimization):
- Best for: Constrained & complex problems
- MST Degree<=3: 36% better than ACO
- TSP Path: 30% better than ACO
- Strength: Constraints, local search
KEY DIFFERENCES:
* BCO has local search (ACO doesn't)
* BCO has abandonment (ACO doesn't)
* BCO has waggle dance (direct comm.)
* BCO has role differentiation
RECOMMENDATION:
-> Use ACO for simple problems
-> Use BCO for constrained problems
-> Compare both for your case!

🐝 BEE COLONY OPTIMIZATION (BCO) FOR MST PROBLEM
================================================================================
**KEY DIFFERENCES: BCO vs ACO**
================================================================================
ACO:
• All ants construct solutions independently
• Indirect communication via pheromone trails
• Pheromone updated after all ants finish
• No role differentiation
BCO:
• 🐝 SCOUT BEES: Random exploration
• 🐝 EMPLOYED BEES: Exploit current solutions
• 🐝 ONLOOKER BEES: Select best solutions (waggle dance)
• Direct communication (fitness sharing)
• Local neighborhood search
• Abandonment mechanism (poor solutions discarded)
