  abstract =     "This paper presents an approach for constructing
                 improved visual representations of high dimensional
                 objective spaces using virtual reality. These spaces
                 arise from the solution of multi-objective optimisation
                 problems with more than 3 objective functions which
                 lead to high dimensional Pareto fronts. The 3-D
                 representations of m-dimensional Pareto fronts, or
                 their approximations, are constructed via similarity
                 structure mappings between the original objective
                 spaces and the 3-D space. Alpha shapes are introduced
                 for the representation and compared with previous
                 approaches based on convex hulls. In addition, the
                 mappings minimising a measure of the amount of
                 dissimilarity loss are obtained via genetic
                 programming. This approach is preliminarily
                 investigated using both theoretically derived high
                 dimensional Pareto fronts for a test problem (DTLZ2)
                 and practically obtained objective spaces for the 4
                 dimensional knapsack problem via multi-objective
                 evolutionary algorithms like HLGA, NSGA, and VEGA. The
                 improved representation captures more accurately the
                 real nature of the m-dimensional objective spaces and
                 the quality of the mappings obtained with genetic
                 programming is equivalent to those computed with
                 classical optimization algorithms.",
