Implementation of adaptive window size assignment

[tyz1994]

Dear authors,

Thank you for sharing this great work! I really enjoyed reading the paper and am particularly interested in the rejection sampling for adaptive window size.

I've been looking through the source code to understand how this adaptive mechanism is implemented, but I haven't been able to locate the relevant section yet. Would you mind pointing me to the specific files or code lines where this feature is handled?

I'd greatly appreciate your guidance!

Best regards, Terry
