Logic gates that exploit the swarming behaviour of soldier crabs have been built and tested in Japan.
One of the hot topics in computer science is the study of unconventional forms of computation.
This is motivated by two lines of thought. The first is theoretical--ordinary computers are hugely energy inefficient--some eight orders of magnitude worse than is theoretically possible. The second is practical--Nature has evolved many much more efficient forms of computation for specific tasks such as pattern recognition.
Clearly, we ought to be able to do much better--hence the interest in different ways of doing things.
Today, we look at one of the more curious variations on this theme--a computer that exploits the swarming behaviour of soldier crabs.
