## OpenBox: Generalized and Efficient Blackbox Optimization System
**OpenBox** is an efficient and generalized blackbox optimization (BBO) system, which supports the following 
characteristics: 1) **BBO with multiple objectives and constraints**, 2) **BBO with transfer learning**, 3) 
**BBO with distributed parallelization**, 4) **BBO with multi-fidelity acceleration** and 5) **BBO with early stops**.
OpenBox is designed and developed by the AutoML team from the [DAIR Lab](http://net.pku.edu.cn/~cuibin/) at Peking 
University, and its goal is to make blackbox optimization easier to apply both in industry and academia, and help 
facilitate data science.


## Software Artifacts
#### Standalone Python package.
Users can install the released package and use it with Python.
#### Distributed BBO service.
We adopt the "BBO as a service" paradigm and implement OpenBox as a managed general service for black-box optimization. 
Users can access this service via REST API conveniently, and do not need to worry about other issues such as environment 
setup, software maintenance, programming, and optimization of the execution. Moreover, we also provide a Web UI,
through which users can easily track and manage the tasks.


## Design Goal

The design of OpenBox follows the following principles:
+ **Ease of use**: Minimal user effort, and user-friendly visualization for tracking and managing BBO tasks.
+ **Consistent performance**: Host state-of-the-art optimization algorithms; Choose the proper algorithm automatically.
+ **Resource-aware management**: Give cost-model-based advice to users, e.g., minimal workers or time-budget.
+ **Scalability**: Scale to dimensions on the number of input variables, objectives, tasks, trials, and parallel 
  evaluations.
+ **High efficiency**: Effective use of parallel resources, system optimization with transfer-learning and 
  multi-fidelities, etc.
+ **Fault tolerance**, **extensibility**, and **data privacy protection**.

+ **OpenBox** based solutions achieved the **First Place** of 
  [ACM CIKM 2021 AnalyticCup](https://www.cikm2021.org/analyticup)
  (Track - Automated Hyperparameter Optimization of Recommendation System).
+ **OpenBox** team won the **Top Prize (special prize)** in the open-source innovation competition at 
  [2021 CCF ChinaSoft](http://chinasoft.ccf.org.cn/papers/chinasoft.html) conference.
+ [**Pasca**](https://github.com/PKU-DAIR/SGL), which adopts Openbox to support neural architecture search 
  functionality, won the **Best Student Paper Award at WWW'22**.

## Installation

### System Requirements

Installation Requirements:
+ Python >= 3.7 (Python 3.7 is recommended!)

Supported Systems:
+ Linux (Ubuntu, ...)
+ macOS
+ Windows

We **strongly** suggest you to create a Python environment via 
[Anaconda](https://www.anaconda.com/products/individual#Downloads):
```bash
conda create -n openbox python=3.7
conda activate openbox
```

Then we recommend you to update your `pip`, `setuptools` and `wheel` as follows:
```bash
pip install --upgrade pip setuptools wheel
```

### Installation from PyPI

To install OpenBox from PyPI:

```bash
pip install openbox
```

For advanced features, [install SWIG](https://open-box.readthedocs.io/en/latest/installation/install_swig.html)
first and then run `pip install "openbox[extra]"`. 

### Manual Installation from Source

To install the newest OpenBox from the source code, please run the following commands:
```bash
git clone https://github.com/PKU-DAIR/open-box.git && cd open-box
pip install .
```

Also, for advanced features, [install SWIG](https://open-box.readthedocs.io/en/latest/installation/install_swig.html)
first and then run `pip install ".[extra]"`.

For more details about installation instructions, please refer to the 
[Installation Guide](https://open-box.readthedocs.io/en/latest/installation/installation_guide.html).

## Quick Start

A quick start example is given by:

```python
import numpy as np
from openbox import Optimizer, space as sp

# Define Search Space
space = sp.Space()
x1 = sp.Real("x1", -5, 10, default_value=0)
x2 = sp.Real("x2", 0, 15, default_value=0)
space.add_variables([x1, x2])

# Define Objective Function
def branin(config):
    x1, x2 = config['x1'], config['x2']
    y = (x2-5.1/(4*np.pi**2)*x1**2+5/np.pi*x1-6)**2+10*(1-1/(8*np.pi))*np.cos(x1)+10
    return {'objectives': [y]}

# Run
if __name__ == '__main__':
    opt = Optimizer(branin, space, max_runs=50, task_id='quick_start')
    history = opt.run()
    print(history)
```

The example with multi-objectives and constraints is as follows:

```python
import matplotlib.pyplot as plt
from openbox import Optimizer, space as sp

# Define Search Space
space = sp.Space()
x1 = sp.Real("x1", 0.1, 10.0)
x2 = sp.Real("x2", 0.0, 5.0)
space.add_variables([x1, x2])

# Define Objective Function
def CONSTR(config):
    x1, x2 = config['x1'], config['x2']
    y1, y2 = x1, (1.0 + x2) / x1
    c1, c2 = 6.0 - 9.0 * x1 - x2, 1.0 - 9.0 * x1 + x2
    return dict(objectives=[y1, y2], constraints=[c1, c2])

# Run
if __name__ == "__main__":
    opt = Optimizer(CONSTR, space, num_objectives=2, num_constraints=2,
                    max_runs=50, ref_point=[10.0, 10.0], task_id='moc')
    history = opt.run()
    history.plot_pareto_front()  # plot for 2 or 3 objectives
    plt.show()
```

We also provide **HTML Visualization**. Enable it by setting additional options
`visualization`=`basic`/`advanced` and `auto_open_html=True`(optional) in `Optimizer`:

```python
opt = Optimizer(
    ...,
    visualization='advanced',  # or 'basic'. For 'advanced', run 'pip install "openbox[extra]"' first
    auto_open_html=True,       # open the visualization page in your browser automatically
    task_id='example_task',
    logging_dir='logs',
)
history = opt.run()
```

For more visualization details, please refer to 
[HTML Visualization](https://open-box.readthedocs.io/en/latest/visualization/visualization.html).
