AI-Complete, AI-Hard, or AI-Easy - Classification of Problems in AI

The paper contributes to the development of the theory of AI-Completeness by formalizing the notion of AIComplete and AI-Hard problems. The intended goal is to provide a classification of problems in the field of General Artificial Intelligence. We prove Turing Test to be an instance of an AI-Complete problem and further show numerous AI problems to be AI-Complete or AI-Hard via polynomial time...
