@rlacjfjin thanks for opening an issue!
I find it difficult to understand your question. What's the same as what? Can you perhaps rephrase, or explain in more detail?

I think ThresholdAccept and RecordToRecordTravel are same codes in call function.
Is it true?
from alns.
No, TA compares against the current solution; RRT against the global best:
>>>diff RecordToRecordTravel.py ThresholdAccept.py
< def __call__(self, rnd, best, current, candidate):
< # This follows from the paper by Dueck (1993), p. 87.
< result = (candidate.objective() - best.objective()) <= self._threshold
---
> def __call__(self, rnd, best, curr, cand):
> # This follows from the paper by Dueck and Scheueur (1990), p. 162.
> res = cand.objective() - curr.objective() <= self._threshold
Do note that these APIs are not yet set in stone - they are not yet released. In particular, I suspect we might merge RRT and TA into one class, and have the behaviour depend on a parameter.

I'm following your project, and I see new submissions.
I've checked what has changed, sorry for disturbing you.
It's ok now,
thanks

No worries, I am glad we could clear this up!
