(The size of the bzip2 file is\napproximately 14 gigabytes; the unzipped data is approximately 36\ngigabytes.)\n\nThe databases contain, for each type, state size, and multiplier size,\nspectral scores (e.g., `LCG-128-128` for spectral scores of 128-bit\nmultipliers for LCGs with 128 bits of state) and lagged spectral scores\n(e.g., `MCG-128-3-64` for 3-lagged scores of 64-bit multipliers for MCGs\nwith 128 bits of state). For each multiplier we list the minimum score\nfrom dimension 2 to dimension 8, the harmonic score (see the paper) from\ndimension 2 to dimension 8, the multiplier in decimal and hexadecimal\nform, and finally the spectral scores from dimension 2 to dimension 8.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvigna%2Fcprng","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fvigna%2Fcprng","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvigna%2Fcprng/lists"}
