The search for signals from extraterrestrial civilizations.The probability that a star has a habitable planet with a communicative civilization is investigated. One approach to the search problem is to assume that the other civilization will do most of the work, which implies that the search is limited to 'supercivilizations' able to transmit detectable signals in all directions all the time. The development of an optimal search strategy is discussed together with questions of the probability of success.
