Artificial Life is the first unifying forum for the dissemination of scientific and engineering research in the field of artificial life. It reports on synthetic biological work being carried out in any and all media, from the familiar "wetware" of organic chemistry, through the inorganic "hardware" of mobile robots, all the way through the virtual "software" residing inside computers. Artificial Life is an essential resource for scientists and academics researching artificial life, robotics, artificial intelligence, neural networks, genetic algorithms, ecosystem dynamics, and origin of life.
