Description

The color refinement algorithm is a heuristic method to detect whether two graphs are isomorphic (see, e.g., [GKMS17+]). It is also known as the 1-dimensional Weisfeiler-Leman algorithm.

Development

Install the development tools:

yarn

Start an http server for local development:

yarn run http-server

Manually run the JavaScript linter standard:

yarn run standard

Manually run the CSS linter stylelint:

yarn run stylelint "**/*.css"

Both linters support --fix for automatic fixing.

Visual Studio Code provides the extensions chenxsan.vscode-standardjs and stylelint.vscode-stylelint for automatic linting.

Built with

• D3.js
• CSS grid
• normalize.css
