the concept
The Concept
  • Aesthetic, emotional, and empathetic selection are applied to a derivative of Karl Sims\'Evolved Virtual Creatures.
  • The resulting Creatures can be beautiful or strange, and provoke strong reactions in human observers.
  • It may be possible to evolve virtual pets to which humans can form strong emotional bonds.

Coming Enhancements
  • Genome editor
  • Hybrid GA / aesthetic selection
  • Co-evolutionary scenarios
sims automated evolution
Sims’ Automated Evolution
  • Karl Sims used a GA to automate evolution
  • With selection for:
    • Swimming speed
    • Crawling/walking speed
    • Jumping height
    • Ability to follow
sims co evolution
Sims’ Co-evolution
  • Karl Sims used GA selection for possession of a block
  • to create a co-evolutionary scenario
ray s co evolution
Ray’s Co-evolution
  • Rather than using GA selection for competition
  • I will evolve my creatures to love
  • By selecting for:
    • Moving towards one another
    • Maximum surface contact
    • Continued relative movement while in contact
