While use of the attribute-value framework is widespread in RL, it has limited expressive power. Logic languages, such as first-order logic, provide a more expressive framework, and their use in RL has led to the field of relational RL. This thesis develops a system for relational RL based on learning classifier systems (LCS). In brief, the system generates, evolves, and evaluates a population of condition-action rules, which take the form of definite clauses over first-order logic. Adopting the LCS approach allows the resulting system to integrate several desirable qualities: model-free and \"tabula rasa\" learning; a Markov Decision Process problem model; and importantly, support for variables as a principal mechanism for generalisation. The utility of variables is demonstrated by the system's ability to learn genuinely scalable behaviour - behaviour learnt in small environments that translates to arbitrary large versions of the environment without the need for retraining.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838301969\"\u003e\u003ch3\u003eA Learning Classifier System Approach to Relational Reinforcement Learning\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783838301969","offer_id":39459751919709,"sku":"9783838301969","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/3e733f08-b72f-45d3-9929-ec99af1fbf18.jpg?v=1772778636","url":"https:\/\/shop.autorenwelt.de\/en\/products\/reinforcement-learning-logic-and-evolutionary-computation-a-learning-classifier-system-approach-to-relational-reinforcement-learning-von-drew-mellor","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
