```

---

## 📊 Usage Examples

### Benchmarking an Optimization Algorithm

```
import numpy as np
from optimization_benchmarks import ackley, rastrigin, sphere

def my_optimizer(func, bounds, max_iter=1000):
"""Your optimization algorithm here."""
# ... implementation ...
pass

test_functions = {
'Sphere': (sphere, [(-5.12, 5.12)] * 10),
'Ackley': (ackley, [(-32, 32)] * 10),
'Rastrigin': (rastrigin, [(-5.12, 5.12)] * 10),
}

for name, (func, bounds) in test_functions.items():
best_x, best_f = my_optimizer(func, bounds)
print(f"{name}: f(x*) = {best_f}")
```

---

## 🎯 Using Benchmark Metadata (v0.1.1+)

Version 0.1.1 introduces comprehensive metadata for all 55 functions, eliminating the need to manually specify bounds and known minima:

```
from optimization_benchmarks import BENCHMARK_SUITE, get_function_info
import numpy as np
```

### Get all available functions

```
from optimization_benchmarks import get_all_functions
print(f"Total functions: {len(get_all_functions())}") # 55
```

### Get metadata for a specific function
```
info = get_function_info('ackley')
func = info['function']
bounds = info['bounds'] * info['default_dim'] # 10D by default
known_min = info['known_minimum']
```

### Test at known minimum
```
x = np.zeros(info['default_dim'])
result = func(x)
print(f"Ackley(0) = {result:.6f}, Expected: {known_min}")
```

### Simple Benchmarking with Metadata
```
from optimization_benchmarks import BENCHMARK_SUITE
import numpy as np

def simple_random_search(func, bounds, n_iter=1000):
"""Simple random search optimizer."""
best_x = None
best_cost = float('inf')

for _ in range(n_iter):
    x = np.array([np.random.uniform(b, b) for b in bounds])[1]
    cost = func(x)
    if cost < best_cost:
        best_cost = cost
        best_x = x

return best_x, best_cost
```
Benchmark on all functions - no manual bounds needed!
```
for name, meta in BENCHMARK_SUITE.items():
func = meta['function']
bounds = meta['bounds'] * meta['default_dim']
known_min = meta['known_minimum']
```
```
best_x, best_cost = simple_random_search(func, bounds)
error = abs(best_cost - known_min)

print(f"{name:20s} | Found: {best_cost:12.6f} | "
      f"Expected: {known_min:12.6f} | Error: {error:10.6f}")
```
