AI Usage Guide: Humpday Optimization

Quick Start for AI Assistants

This repository provides validated, production-ready optimization algorithms in both Python and JavaScript. Here's how to quickly help users with optimization tasks:


Python Package (Recommended)

Install & Use

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}")

Why Reliable

  • 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

🌐 JavaScript Algorithms (Browser/Node)

Direct CDN Usage

<!-- Include in any webpage -->
<script src="https://microprediction.github.io/humpday/js/optimizers.js"></script>

<script>
// Use any algorithm directly

}

const optimizer = new PRIMA_UOBYQA(objective, 100, 2);

🚀 Common Use Cases for AIs

1. Help User Choose Algorithm

# When user asks "what optimizer should I use?"
from humpday import suggest

# Recommend based on problem characteristics
best = suggest(user_objective, n_dim=problem_dim, n_trials=budget)

2. Interactive Optimization Demo

// For educational/visualization purposes
const visualizer = new AlgorithmVisualizer('container-id');
// Creates interactive 3D optimization demonstration

3. Quick Prototyping

# Fast optimization without choosing algorithm
from humpday import minimize

result = minimize(objective, bounds=[(0,10), (0,10)], n_trials=100)

4. Algorithm Comparison

# Compare multiple algorithms
from humpday.optimizers.alloptimizers import OPTIMIZERS

for name, optimizer in OPTIMIZERS.items():
    if callable(optimizer):
        result = optimizer(objective, n_dim=2, n_trials=50)
        print(f"{name}: {result}")

5. Rectangular Domain Extension (Key Pattern)

# Most algorithms work on [0,1]^n - here's how to extend to any bounds
def create_bounded_optimizer(bounds):
    """
    Thin wrapper to optimize on arbitrary rectangular domains
    
    Args:
        bounds: List of (min, max) tuples for each dimension
        
    Returns:
        Optimizer function that works on specified bounds
    """
    
    def bounded_objective_wrapper(original_objective):
        def unit_cube_objective(x_unit):
            # Transform from [0,1]^n to actual bounds
            x_real = []
            for i, (low, high) in enumerate(bounds):
                x_real.append(low + x_unit[i] * (high - low))
            
            return original_objective(x_real)
        return unit_cube_objective
    
    def optimize(objective, algorithm='auto', n_trials=100):
        # Wrap objective for unit cube
        wrapped_obj = bounded_objective_wrapper(objective)
        
        # Use any humpday algorithm (all work on [0,1]^n)
        if algorithm == 'auto':
            from humpday import suggest
            optimizer = suggest(wrapped_obj, n_dim=len(bounds), n_trials=n_trials)
        else:
            optimizer = algorithm
            
        result_unit = optimizer(wrapped_obj, n_dim=len(bounds), n_trials=n_trials)
        
        # Transform result back to real bounds
        result_real = []
        for i, (low, high) in enumerate(bounds):
            result_real.append(low + result_unit[i] * (high - low))
            
        return result_real
    
    return optimize

# Example usage:
def my_objective(x):
    # Optimize on domain: x[0] ∈ [-10, 10], x[1] ∈ [0, 100] 
    return (x[0] - 2)**2 + (x[1] - 50)**2

bounds = [(-10, 10), (0, 100)]
optimizer = create_bounded_optimizer(bounds)
best_point = optimizer(my_objective, n_trials=200)
print(f"Optimum at: {best_point}")

6. JavaScript Rectangular Domain Extension

// Similar pattern for browser/JavaScript optimization
function createBoundedOptimizer(bounds) {
    function boundedObjectiveWrapper(originalObjective) {
        return function(x_unit) {
            // Transform from [0,1]^n to actual bounds  
            const x_real = x_unit.map((val, i) => {
                const [low, high] = bounds[i];
                return low + val * (high - low);
            });
            return originalObjective(x_real);
        };
    }
    
    function optimize(objective, algorithmClass = PRIMA_UOBYQA, nTrials = 100) {
        const wrappedObj = boundedObjectiveWrapper(objective);
        const optimizer = new algorithmClass(wrappedObj, nTrials, bounds.length);
        const result = optimizer.optimize();
        
        // Transform result back to real bounds
        const realResult = result.bestX.map((val, i) => {
            const [low, high] = bounds[i];
            return low + val * (high - low);
        });
        
        return {
            bestX: realResult,
            bestValue: result.bestValue,
            evaluations: result.evaluations
        };
    }
    
    return optimize;
}

// Example:
function myObjective(x) {
    // Domain: x[0] ∈ [-5, 5], x[1] ∈ [10, 20]
    return Math.pow(x[0] - 1, 2) + Math.pow(x[1] - 15, 2);
}

const bounds = [[-5, 5], [10, 20]];
const optimizer = createBoundedOptimizer(bounds);
const result = optimizer(myObjective, NelderMead, 150);
console.log("Optimum:", result.bestX, "Value:", result.bestValue);
