## Fitness Function Components
|
||||
|
||||
The algorithm optimizes for multiple objectives:
|
||||
|
||||
### 1. Capacity Efficiency (40% weight)
|
||||
- Perfect match: 1.0
|
||||
- <10% waste: 1.0
|
||||
- <30% waste: 0.8
|
||||
- <50% waste: 0.6
|
||||
- >50% waste: 0.4
|
||||
- Overfilled: 0.0
|
||||
|
||||
### 2. Time Preference Satisfaction (30% weight)
|
||||
- Within 30 minutes: 1.0
|
||||
- Within flexibility window: 0.8 - 0.5
|
||||
- Beyond flexibility: max(0.0, 0.5 - penalty)
|
||||
|
||||
### 3. Conflict Penalty (20% weight)
|
||||
- No conflicts: 1.0
|
||||
- Each conflict: -0.5 penalty
|
||||
|
||||
### 4. Resource Matching (10% weight)
|
||||
- Based on classroom resources and subject requirements
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Basic Optimization
|
||||
|
||||
```python
|
||||
from app.models.genetic_algorithm import ReservationOptimizer
|
||||
|
||||
optimizer = ReservationOptimizer()
|
||||
|
||||
# Optimize for specific commissions
|
||||
result = optimizer.optimize_schedule(
|
||||
commission_ids=[1, 2, 3],
|
||||
admin_user_id=1,
|
||||
start_date=datetime(2024, 1, 15),
|
||||
end_date=datetime(2024, 1, 20)
|
||||
)
|
||||
|
||||
print(f"Fitness Score: {result['fitness_score']}")
|
||||
print(f"Reservations Created: {result['assigned_reservations']}")
|
||||
```
|
||||
|
||||
### Applying Optimized Reservations
|
||||
|
||||
```python
|
||||
# Apply to database
|
||||
reservations = optimizer.apply_optimized_reservations(result['reservations'])
|
||||
print(f"Applied {len(reservations)} reservations")
|
||||
```
|
||||
|
||||
### API Usage

||||
- Space Complexity: O(P × N)
|
||||
|
||||
### Scalability:
|
||||
- Handles 50+ reservation requests efficiently
|
||||
- Configurable population size for larger datasets
|
||||
- Parallel evolution possible for very large datasets
|
||||
|
||||
## Configuration Options
|
||||
|
||||
### Algorithm Parameters (can be modified in routes):
|
||||
```python
|
||||
genetic_algorithm = GeneticAlgorithm(
|
||||

|
||||
generations=200, # Increase for convergence
|
||||
mutation_rate=0.15, # Adjust diversity
|
||||
crossover_rate=0.85 # Adjust inheritance
|
||||
)
|
||||
```
|
||||
|
||||
### Fitness Weights (can be tuned):
|
||||
```python
|
||||
# In Individual.calculate_fitness()
|
||||
score += capacity_score * 0.4 # 40% weight
|
||||
score += time_score * 0.3 # 30% weight
|
||||
score += conflict_score * 0.2 # 20% weight
|
||||
score += resource_score * 0.1 # 10% weight
|
||||
```
|
||||
|
||||
## Monitoring and Debugging

## 🔄 Workflow Integration
|
||||
|
||||
### Before Integration
|
||||
- Users navigate separately to genetic algorithm
|
||||
- No context from current schedule
