The issue of the allow_full_rewrites

[Ethan-han921]

When I tried to use the 'allow_full_rewrites' to update the code, I also found the problem that sometimes, it could lose the EVOLVE-BLOCK-START / END markers. Then, I checked the issues-106 .

I saw that you have removed it. Meanwhile, I checked your update.

cfb3022#diff-463219ee5ff29defd64e3ccdec7940e9660053d4d04096075577cfe3416c694f

But it's so weird. For your updated code in openai/controller. py, there is the code about full_rewrite_user, these three lines.

However, in your main branch openai/controller. py, there is no code about it.

.

Could you please check or review the code? Thanks for your time.

I removed the allow_full_rewrite config as having two configs (allow_full_rewrite and diff_based_evolution) for the same thing was confusing. So, to do full rewrite you can set the diff_based_evoution to false. When you use that the EVOLVE-BLOCK-START / END markers are not going to be used, the LLM will be free to rewrite the entire code.

I see. Thank you so much. Could you please check the controller.py in the main branch? Since I didn't find out changed part in controller.py based on cfb3022#diff-463219ee5ff29defd64e3ccdec7940e9660053d4d04096075577cfe3416c694f

• If diff-based: Extracts diffs and applies them to parent code
• • If full rewrite: Parses the complete new program from LLM response
