While we’re widely interested in the field of digital evolution/artificial life at the Devolab, we have various more specific projects currently being investigated. We’re planning on trying to keep the Projects page up-to-date whenever a new major project is undertaken or an old one wrapped up (hopefully with a publication to share!), I decided to draw your attention to our current work now that everything is up-to-date:
Hello, world, we’re back! The Devolab (i.e. Dr. Charles Ofria’s research lab) has been up to lots of research, but not much blogging – until now. We’ve got lots of plans for discussing interesting papers, ongoing research, behind-the-scenes looks at grad student life, and much more. For now, plan on seeing new posts on Tuesdays. To start things off, we thought you’d like to know what we’ve been up to in the past year or so, therefore here is a list of the recent publications from the lab. Going forward, we’ll aim to have posts with high-level discussions of our new papers, and slowly fill in with posts about some of the more exciting previous papers. Without further ado, we present research:
Several new Devolab publications have been accepted to appear at Artificial Life 13. “Digital Evolution Exhibits Surprising Robustness to Poor Design Decisions” by David M. Bryson and Charles Ofria Abstract When designing an evolving software system, a researcher must set many aspects of the representation and inevitably make arbitrary decisions. Here we explore the consequences of poor design decisions in the development of a virtual instruction set in digital evolution systems. We evaluate the introduction of three different severities of poor choices. (1) functionally neutral instructions that water down mutational options, (2) actively deleterious instructions, and (3) a lethal die instruction. We further examine the impact of a high level of neutral bloat on the short term evolutionary potential of genotypes experiencing environmental change. We observed surprising robustness to these poor design decisions across all seven […]
Our work was the cover story of the Feb. 2005 issue of Discover magazine. [text]
At the MSU Digital Evolution Laboratory (Devolab), we perform experimental studies on digital organisms with the twin goals of improving our understanding of how natural evolution works, and applying this knowledge to solving computational, engineering, and biological problems.
