The University of Maryland research group behind Geneva, which uses genetic algorithms to find ways around nation-state internet censorship.
What HN saysCommenters cite it as evidence that automated methods can bypass the Great Firewall, including its filtering of SNI and ESNI, and link its papers.

The Great Firewall is bypassed by getoutline.com (self-hosted, open source), getlantern.io (once open source), and psiphon.ca (open source). There are also several other efforts that bundle multiple strategies like V2Ray.
