evo devo robo

"Forget what you see in movies. Most robots sit in a factory somewhere doing dull, repetitive work. Even if their software does dream of a more interesting job, their physical form remains fixed from the day they’re assembled to the moment they’re junked. But it doesn’t have to be that way, say pioneers of `evo devo robo`—evolutionary developmental robotics, which applies principles of natural selection and biological development to machine design."

Development of antibiotic regimens using graph based evolutionary algorithms

"evolutionary algorithms in the development of antibiotic regimens given to production animals. [...] Treatment regimens were found that provided decreased antibiotic resistance relative to conventional methods while providing nearly the same benefits as conventional antibiotic regimes. By using a graph to control the information flow in the evolutionary algorithm, a variety of solutions along the Pareto front can be found automatically for this and other multi-objective problems." Full paper @ BioSystems
