(Phys.org)—Inspired by natural selection and the concept of "survival of the fittest," genetic algorithms are flexible optimization techniques that can find the best solution to a problem by repeatedly selecting for and ...
Last week my sister sent me a great article from Buzzfeed on "a reptile dysfunction". It's about stupid people who buy cute little baby tortoises that, after a few sweet months, enter a growth spurt and rapidly begin to assume ...
