human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups authors who co-authored the same paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "Multi-objective model selection for support vector machines"):
  Abstract: In this article, model selection for support vector machines is viewed as a multi-objective optimization problem, where model complexity and training accuracy define two conflicting objectives. Different optimization criteria are evaluated: Split modified radius margin bounds, which allow for comparing existing model selection criteria, and the training error in conjunction with the number of support vectors for designing sparse solutions.

Includes members:
  Member "Speeding up backpropagation using multiobjective evolutionary algorithms":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "Evolving neural networks through augmenting topologies")
  Member "Covariance Matrix Adaptation for Multi-objective Optimization":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "S-metric calculation by considering dominated hypervolume as klee's measure problem")

Question: Please tell me which research area the co-authored paper (i.e., the source paper of the center hyperedge) belongs to. The 4 classes are: Computer science, Mathematics, Engineering, Economics, Psychology, Business. Directly output the class name.
