human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups papers that share a common citing paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "Environments with Classifier Systems (Experiments on Adding Memory to XCS)"):
  Abstract: Pier Luca Lanzi Technical Report N. 97.45 October 17 th , 1997

Includes members:
  Member "A Study of the Generalization Capabilities of XCS":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "GENETIC AND NON GENETIC OPERATORS IN ALECSYS")

Question: Please tell me which class the citing paper (i.e., the source paper of the center hyperedge) belongs to. The 7 classes are: Neural_Networks, Reinforcement_Learning, Probabilistic_Methods, Theory, Genetic_Algorithms, Case_Based, Rule_Learning. Directly output the class name.

gpt: Reinforcement_Learning
