about data set

[Y-Adel]

I am a Master degree student at the faculty of computer and information technology, assiut university , cairo.
my research is about finding minimum vertex cover using differential evolution algorithm ,after a deep research i found your data set on github and it was so productive with my algorithm .i have already finished my first paper and it is almost ready for publication but it is missing the section of comparison with another published paper to be referenced and fully completed .
I Am asking if these data sets have been cited before in any published paper so I can use it as a reference to compare with my results.
thanks in advance.
