This repository provides validated, production-ready optimization algorithms in both Python and JavaScript. Here's how to quickly help users with optimization tasks:
pip install humpday
# or
uv add humpday
# Simple optimization example
from humpday import suggest
import numpy as np
def objective(x):
return sum(x**2) # Minimize this
# Get best optimizer recommendation
best_algo = suggest(objective, n_dim=3, n_trials=100)
result = best_algo(objective, n_dim=3, n_trials=100)
print(f"Optimum: {result}")- 50+ algorithms from SciPy, Optuna, HyperOpt, Ax-Platform, NeverGrad, etc.
- ✅ Elo ratings from thousands of tests across different problem types
- ✅ Automatic recommendation - suggests best algorithm for your problem
- ✅ Common syntax - same interface across all optimizers
