Assistant Professor Robert MacCurdy and his collaborators have won the for their outstanding contributions in the field of genetic and evolutionary computation.
The award recognizes up to three papers a year that were published in the 10 years earlier and have amassed a high level of citations and deemed to be seminal. Their paper, titled “,” was the only paper to receive the award in 2023.
MacCurdy coauthored the paper along with , and , the latter being the head of the , where MacCurdy and his collaborators met and did the work.
The paper was inspired by the created by ; in his research, Sims demonstrated that computational evolution can produce morphologies that resemble natural organisms, but the potential for increasingly complex and natural morphologies hit a ceiling. It was hypothesized that the limitation in morphological types was due to the rigidity of the materials used in the design space and the direct encoding.
Addressing these problems in their paper, MacCurdy and his collaborators demonstrated how computational evolution can be pushed further through the creation of soft robots and the use of generative, evolutionary-based encoding that wielded the power of multi-objective optimization.
“When you’re trying to solve a design problem, it’s smart to show some humility because you don’t ever fully know the true nature of the problem,” said MacCurdy, “so it’s appealing to use a multi-objective design framework that gives you a whole population of very different solutions to that set of design objectives.”
Using their novel approach, MacCurdy and his collaborators were able to create a set of virtual robots whose locomotion resembled animals found in the natural world but also creatures whose gait was wildly idiosyncratic and unique.
“Some robots galloped like a horse. Others had the running gait of a dog or rolled along like a walrus,” MacCurdy said. “I think these designs were able to capture people’s imagination, while also motivating the use of generative algorithms and multi-objective optimization to solve challenging design problems, and that’s why the paper continues to garner citations and serve as an inspiration for others.”
