  text: 'While finding minimum-cost spanning trees (MST) in undirected graphs is solvable
    in polynomial time, the multi-criteria minimum spanning tree problem (mcMST) is
    NP-hard. Interestingly, the mcMST problem has not been in focus of evolutionary
    computation research for a long period of time, although, its relevance for real
    world problems is easy to see. The available and most notable approaches by Zhou
    and Gen as well as by Knowles and Corne concentrate on solution encoding and on
    fairly dated selection mechanisms. In this work, we revisit the mcMST and focus
    on the mutation operators as exploratory components of evolutionary algorithms
    neglected so far. We investigate optimal solution characteristics to discuss current
    mutation strategies, identify shortcomings of these operators, and propose a sub-tree
    based operator which offers what we term Pareto-beneficial behavior: ensuring
    convergence and diversity at the same time. The operator is empirically evaluated
    inside modern standard evolutionary meta-heuristics for multi-criteria optimization
    and compared to hitherto applied mutation operators in the context of mcMST.'

  text: We derive a class of computationally inexpensive linear dimension reduction
    criteria by introducing a weighted variant of the well-known K-class Fisher criterion
    associated with linear discriminant analysis (LDA). It can be seen that LDA weights
    contributions of individual class pairs according to the Euclidean distance of
    the respective class means. We generalize upon LDA by introducing a different
    weighting function
