Co-evolving designers and critics Bio-inspired design processes
Gregory Hornby, UC Santa CruzJordan Pollack, Brandeis University
Hod Lipson, Cornell University
Conclusions
• Evolutionary design– Open ended, creative– Challenged by scalability, vague design goals
• Evolve designers, not designs– Generative systems that capture design rules
• Evolve critics that represent user tastes– Provoke users to learn their goals & preferences
• Algebra of user models and designers– Use multiple models to influence multiple designers
Evolution
Lipson & Pollack, Nature 406, 2000
X-band antenna for NASA's ST-5 Mission
Evolving Photonic Structures
With Preble, Gondarenko, Robinson, Physical Review Letters, May 2006
Kinematic Synthesis
Peaucelier (1873)Silverster-Kempe (1877)
• Evolutionary design– Open ended, creative– Challenged by scalability, vague design goals
Evolving Designers
Encoding designers with Modularity, Regularity and Hierarchy
Design Program: Executed Instructions:
Graphical version:
Evolving Table DesignersEvolving tables: fitness = height*surface area*stability/material.
No MRH enabled: MRH enabled:
Evolved TablesTable fitness = height*surface*volume / material
Families of Designs
Height: 8 16 24 32
• A single design program can be used to evolve a family of designs:
