In this paper we address the role of modelling creativity in Artificial Intelligence using a Genetic or Evolutionary paradigm approach, and the Knowledge Representation of the universe of discourse using Extended Logic Programming paradigm to handle with incomplete information in evolutionary environments. We present a new computational model approach for the creation of evolutive systems that materializes the knowledge representation and symbolic reasoning mechanisms. Using the evolutionary programming paradigm, the candidate solutions are seen as evolutionary logic programs or theories, being the test whether a solution is optimal based on a measure of the quality-of- information carried out by those logical theories or programs. From the...
