A search engine is provided for searching, evaluating and/or optimizing an emergent model on a computer network. The emergent model is created by independently generating, publishing references to, and subscribing to data objects and/or function objects in a manner free of a globally predefined data object and/or function object definition. Messages are sent to referencing data objects and/or function objects when referenced data objects and/or function objects change. Functions within the function objects are solved when the messages are received. The data objects and/or the function objects are stored in a distributed manner across multiple computing devices on a computer network. At least one of the data objects is defined as an input data object and at least one of the data objects is defined as an output data object to a search engine, the search engine generating changes to the input data object until the output data object satisfies a predefined criteria.
