The repository is structured as follows:

Commits

Manual/Automaic/Both : All commits grouped by NFP and repository. Either only manually mined, automatically mined, or both

ByRepo: Commits split by repository in whoich they were found

Repository Name: Repository containing commits

executionTime.txt: Execution Time improving commits

memory.txt: Memory improving commits

bandwidth.txt: Bandwidth improving commit

frameRate.txt: Frame rate improving commits

Categories: Commits group by category of improvement

executionTime

memory

bandwidth

frameRate

Scripts: A repository cotaining python scripts used to mine commits.

classifier : The automatic commit classifier and the results of our experiments, as described in the appendix of the paper

NOTES Empty files are present where no commits of that group were found.
