                 surpasses traditional evolutionary approaches to
                 solving symbolic regression problems. However, existing
                 GEP algorithms still suffer from premature convergence
                 and slow evolution in anaphase. Aiming at these
                 pitfalls, we designed a novel evolutionary algorithm,
                 namely Uniform Design-Aided Gene Expression Programming
                 (UGEP). UGEP uses (1) a mixed-level uniform table for
                 generating initial population and (2) multiparent
                 crossover operators by taking advantages of the
                 dispersibility of uniform design. In addition to a
                 theoretic analysis, we compared UGEP to existing GEP
                 variants via a number of experiments in dealing with
                 symbolic regression problems including function fitting
                 and chaotic time series prediction. Experimental
                 results indicate that UGEP excels in terms of both the
                 capability of achieving the global optimum and the
                 convergence speed in solving symbolic regression
