  abstract =     "This study examines the usefulness of employing digit
                 concatenation, as distinct from the traditional
                 expression based approach, for the purpose of evolving
                 constants in Grammatical Evolution. Digit concatenation
                 involves creating constants (either whole or real
                 numbers) by concatenating digits to form a single
                 value. The two methods are compared using three
                 different problems, which are finding a static real
                 constant, finding dynamic real constants, and a
                 quadratic map, which on iteration generates a chaotic
                 time-series. The results indicate that the digit
                 concatenation approach results in a significant
                 improvement in the best fitness obtained across all
                 problems analysed here.",
