Questions about RGPE codes

[JIEUN-12]

Hi, I'm researching automatic database tuning and have had a chance to read your paper.
I have read your paper with great interest!

I want to execute your project, however, I can't understand the work process of RGPE (specifically tune_RGPE() function). I saw openbox library and your code detailed, and found that a version of the openbox that you have used is a previous version. Therefore, I hit a wall to understand the RGPE process.

You said that RGPE is an algorithm that transfers historical experience, so I'm curious where in your code the transfer of history and the part of the ranking loss you described in your paper are.

I would be grateful for your answer.
