## Algorithms

| Algorithm | Type | Convergence | Best For |
|-----------|------|-------------|----------|
| **PSO** | Particle Swarm | Fast | Unimodal, smooth landscapes |
| **ACO** | Ant Colony | Medium | Discrete/combinatorial (TSP) |
| **Firefly** | Attraction-based | Slow but thorough | Multi-modal, many local optima |
| **PSO-Firefly** | Hybrid | Fast + thorough | Complex real-world problems |
| **DE** | Differential Evolution | Medium | High-dimensional continuous |
| **ABC** | Artificial Bee Colony | Medium | Balanced exploration/exploitation |

## Quick Start

```bash
pip install swarmlab
```

```python
from swarmlab import PSO, Rastrigin

# Optimize Rastrigin function in 30 dimensions
optimizer = PSO(
    n_particles=50,
    dimensions=30,
    bounds=(-5.12, 5.12),
    max_iterations=1000,
)

result = optimizer.optimize(Rastrigin())
print(f"Best fitness: {result.best_fitness:.6f}")
print(f"Found at: {result.best_position[:3]}...")  # first 3 dims
```

### Hybrid Algorithm

```python
from swarmlab import HybridPSOFirefly, Ackley

hybrid = HybridPSOFirefly(
    n_particles=60,
    dimensions=30,
    pso_weight=0.7,       # 70% PSO influence
    firefly_weight=0.3,   # 30% Firefly attraction
    switch_iteration=500, # Switch dominance at iter 500
)

result = hybrid.optimize(Ackley())
# Convergence curve auto-saved to results/
```

### Run Ablation Study

```python
from swarmlab import AblationRunner

runner = AblationRunner(
    algorithms=["PSO", "Firefly", "HybridPSOFirefly", "DE"],
    benchmarks=["Rastrigin", "Ackley", "Schwefel", "Griewank"],
    dimensions=[10, 30, 50],
    runs_per_config=30,
)

results = runner.run()
results.to_latex("results/ablation_table.tex")
results.plot_convergence("results/convergence.png")
```
