# PyCIM

PyCIM is the first simulator that can produce the dynamic behavior of CIM. PyCIM effectively capture some characteristic phenomena of DOPO and CIM, including a spontaneous symmetry breaking, threshold behavior, gain saturation, and the process of CIM solving MAX-CUT problems. Additionally, it is built-in time-varying coupling strengths and pump schedules. Moreover, PyCIM can be used for analyzing the impact of parameters on the performance of CIM, and guiding the design and optimization of actual physical systems.

## Requirements

To use the simulator, Python 3.7.7 or above is required.

The following packages are required by the installation:

* matplotlib==3.5.3
* numpy==1.21.5
* scipy==1.7.3
 
#### method 1:

```python
pip install pycim-simulator
```

#### method 2:

The first step is cloning the repository:

```python
git clone https://github.com/shadowforwind/pycim-simulator.git
```

Then, install the following packages:

```python
cd pycim-simulator
pip install -r requirements.txt
```

## Getting started with pycim

The simplest way of familiarize with the pycim-simulator is by exploring the demo case provided in the file ''display.ipynb''. The file ''display.ipynb'' provides step-by-step description of the main commands to: initialize input, transform model, single simulation, result measurement, or solving the Max-Cut problem.
