## Speaker Guidelines

**TL;DR** Do unto others as you would have them do unto you.

At minimum, an AIG presenter should prepare a few slides and an example code.

- The slides should explain: - what the algorithm is - how a minimum example works - why the algorithm might be practically useful
- A code that demonstrates the simplest problem the algorithm solves.
- Make a pull-request (PR) to the website repository to make your presentation and code eternal. Follow instructions in the README.md file.

The presentation should be 30-50 min if given without interruptions. Interactive elements are encouraged. e.g. a Jupyter notebook demo. with tweakable parameters given by the audience.
