Pairwise is a tool for generating configurations using pairwise algorithm with weights.

1. Clone this repo and change to cloned directory.
2. Install pipenv using pip: pip install pipenv
3. Install required packages: pipenv install

Usage of this tool is very simple.

First you need json file with parameters. e.g. parameters.json

{
  "Parameters": {
    "P1": ["a", "b"],
    "P2": [1, 2],
    "P3": ["x", "y"]
  }
}

Then you can run it as pipenv run pairwise parameters.json

You must always run it from the root directory (/path/to/repository/Pairwise).

As output you get generated configurations:

 1: ['a', 2, 'y']
 2: ['a', 1, 'x']
 3: ['b', 1, 'y']
 4: ['b', 2, 'x']

You can also set weights for each parameter. e.g.

{
  "Parameters": {
    "P1": ["a", "b"],
    "P2": [1, 2],
    "P3": ["x", "y"]
  },
  "Weights": {
    "a": 1,
    "x": 2
  }
}

Weight represents the ratio in which you want to parameters appear in generated configuratations. Default weight for each parameter is 1.

Additionally, you can use some of the available options:

• --output {file.csv} creates csv file with generated configurations
• --margin {float} margin of weights, some wiggle room for weight representation in generated configurations (default: 0.05)
• --count prints how many times was each parameter used during configuration generation

e.g. pipenv run pairwise --output configurations.csv --margin 0.04 --count parameters.json
