This is the replication package for Genetic Improvement of Data gives Division free Division (author copy - GI_Data_Gives_Divsion_Free_Division.pdf).

The package contains the source code as described in section IV of the publication and aims to enable the reproduction of section IV b - Automatic changes to data table using CMA-ES and section IV c - Testing the evolved drcp function.

• Publication.pdf author copy of the submission
• gi_cbrt.tar.gz contains the source code the paper was written on, as described in Section IV Evolving DRCP From Free GNU PowerPC SQRT
• dependencies contains libraries needed for replication
  • GNU C Library (glibc) - Download from: https://www.gnu.org/software/libc/. Contained file is the exact version that the submission was conducted with.
• scripts contains various scripts that are supposed to make the replication easier for the user. If there are issues with them, please consult the README.txt in gi_cbrt.tar.gz, the scripts themselves (maybe you are missing packages on linux), or open an issue in
• results contains logs of the executions the publication was based on

• Linux OS - As this work depends on glibc.
• Installation of the following linux packages (intentionally not provided as script, as it would have to be run with root privileges):
  • gunzip sudo apt-get install gzip
  • tar sudo apt-get install tar
  • csh sudo apt-get install csh
  • sed sudo apt-get install sed

Replicate using the following steps:

• (optional) scripts you may need to make scripts executable with chmod +x *.sh
• unpack.sh will unpack to an execution folder (warning execution folder WILL be deleted by unpack), and build glibc
• replicate.sh runs the compilation, CMA-ES execution, and tests of the lookup table
  • replicate per default replicates divide you can also replicate other functions by adding an optional parameter
  • crbt replicates cube root
  • divide replicates division
  • invsqrt replicates root^-1, and also the quake invsqrt comparison
  • log2 replicates log2
• replicate_all.sh will replicate everything and copy the results to different subfolders (results_function)
• You'll know if the replication succeeded when the folder "replication_results" is created and contains:
  • the generated lookup table (t_cbrt.c)
  • the outputs of the test scripts (*.out)

• Installation of the following linux packages (intentionally not provided as script, as it would have to be run with root privileges):
  • rcs sudo apt-get install rcs

Test (not replicate due to different hardware!) using the following steps:

• performance.sh executes the benchmark
• You'll know if the benchmakr succeeded when the folder "performance_results" is created and contains:
  • The outputs of the tests (*.out)
  • benchmarking info of your pc (system_info.txt)
