Darwin Gödel Machine rewrote its own scaffolding to raise SWE-bench scores

The Darwin Gödel Machine, a coding agent from Sakana and Jeff Clune's lab, modified its own codebase over roughly eighty iterations without supervision.

Its additions included better file viewing, patch validation before submitting fixes, generating and ranking several candidate solutions, and keeping a history of failed attempts.

These changes raised its score from 20 to 50 percent on SWE-bench and from 14 to 31 percent on Polyglot.
