Abstract: A method of using applications of pattern recognition or image analysis is disclosed. A request for a content item is received. A version of the content item is selected from a plurality of versions of the content item based on one or more applications of one or more algorithms. The one or more algorithms include one or more image-analysis algorithms, pattern-recognition algorithms, or genetic algorithms. One or more of the plurality of versions has undergone transformation into a plurality of combinations of content segments that comprise the plurality of versions. The one or more algorithms target one or more success rates with respect to one or more metrics. The selected version of the content item is communicated to the device of the user in response to the request.
