- abstract = "Compression, e.g. gzip, gives algorithmic information theory (Kolmogorov Complexity) based measures of string population diversity. To boost it we use the GI tool Magpie and select programs of average fitness that contribute most to variety, allowing evolution to automatically tailor triangle.c for production speed. We calculate C source code diversity via approximations to the Normalised Compression Distance on Multisets (NCDm) using both Cohen and Vitanyi's O(n squared) approach and our own, O(n) method, finding the cheaper, O(n), is equally good.",
