The New Scientist reports that robots that experiments designed by a Swiss research team have artificially evolved ways to communicate with one another. The experiments suggest that simulated evolution could be a useful tool for those designing of swarms of robots. The "genomes" of the bots that found food and avoided poison most efficiently were recombined, mimicking biological natural selection.
Cooperative communication evolved when selective success was judged at the group level – when many robots displayed efficient behaviour – or when the genomes of the robots were most similar – like biological relatives. Posted by Jason McManus.
