## Deriv-free optimizers from many packages in a common syntax, with evaluation

1. There's a [colab notebook](https://github.com/microprediction/humpday/blob/main/black_box_optimization_package_recommender.ipynb) that recommends a black-box derivative-free optimizer for your objective function. 

2. About fifty strategies drawn from various open source packages are assigned [Elo ratings](https://microprediction.github.io/optimizer-elo-ratings/html_leaderboards/overall.html) depending on dimension of the problem and number of function evaluations allowed. 
 
Hello and welcome to HumpDay, a package that helps you choose a Python global optimizer package, and strategy therein, from [Ax-Platform](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/axcube.py), [bayesian-optimization](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/bayesoptcube.py), [DLib](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/dlibcube.py), [HyperOpt](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/hyperoptcube.py), [NeverGrad](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/nevergradcube.py), [Optuna](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/optunacube.py), [Platypus](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/platypuscube.py), [PyMoo](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/pymoocube.py), [PySOT](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/pysotcube.py), Scipy [classic](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/scipycube.py) and [shgo](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/shgocube.py), [Skopt](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/skoptcube.py),
[nlopt](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/nloptcube.py), [Py-Bobyaq](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/bobyqacube.py), 
[UltraOpt](https://github.com/microprediction/humpday/blob/main/humpday/optimizers/ultraoptcube.py) and maybe others by the time you read this. It also presents *some* of their functionality in a common calling syntax.  
 
### Cite or be cited
Pull requests at [CITE.md](https://github.com/microprediction/humpday/blob/main/CITE.md) are welcome. If your package is benchmarked here I'd like to get this bit right.  
 
### Install

See [INSTALL.md](https://github.com/microprediction/humpday/blob/main/INSTALL.md)

Short version:

    pip install humpday
    pip install humpday[full]

## Recommendations

Pass the dimensions of the problem, function evaluation budget and
 time budget to receive [suggestions](https://github.com/microprediction/humpday/blob/main/humpday/comparison/suggestions.py) that are independent of your problem set,
 
        from pprint import pprint 
        from humpday import suggest
        pprint(suggest(n_dim=5, n_trials=130,n_seconds=5*60))
        
where *n_seconds* is the total computation budget for the optimizer (not the objective function) over all 130 function evaluations. Or simply pass your objective function, and it will time it and do something sensible:
     
        from humpday import recommend
    
        def my_objective(u):
            time.sleep(0.01)
            return u[0]*math.sin(u[1])

        recommendations = recommend(my_objective, n_dim=21, n_trials=130)

## Points race
        
If you have more time, call [points_race](https://github.com/microprediction/humpday/blob/main/humpday/comparison/odious.py) on a list of your own objective functions:

        from humpday import points_race
        points_race(objectives=[my_objective]*2,n_dim=5, n_trials=100)
        
See the [colab notebook](https://github.com/microprediction/humpday/blob/main/black_box_optimization_package_recommender.ipynb).

## How it works 

In the background, 50+ strategies are assigned [Elo ratings](https://github.com/microprediction/optimizer-elo-ratings/tree/main/results/leaderboards) by sister repo [optimizer-elo-ratings](https://github.com/microprediction/optimizer-elo-ratings). Oh I said that already. Never mind. 

## Contribute

By all means contribute more to [optimizers](https://github.com/microprediction/humpday/tree/main/humpday/optimizers).
