Welcome to the 2021 Graph Drawing Challenge online submission system!
In this challenge, you will minimize the number of crossings in an upward drawing on a specified grid. A more complete description is available at the challenge description. You can either participate in the manual category (using the provided tool, local participants only), or in the automatic category (use any software you want, open to remote participants as well).
If you wish to participate, please sign in at the top right. After signing in, you can go to the team page to enter your team name and participants. If you are a local participant, also be sure to enter the secret password there.
You can download the input graphs on the problems page, solve them on the tool page, and submit your solutions on the submission page. Finally, you can check out how you are doing on the live scoreboard.
