Article in BIT by Ole Moeller is NOT freely accessible

I have just tried to download this reference from Spain, but unfortunately, it is behind a pay wall of Springer Link. Maybe the author of the wiki page wrote it using an IP to which institutional access is granted... 80.28.105.138 (talk) 06:34, 13 November 2023 (UTC)[reply]

The "doi-access=free" for the BIT article was added by TheMathCat in Special:Diff/1040958672. Any explanation? — Vincent Lefèvre (talk) 14:52, 13 November 2023 (UTC)[reply]

And I've just removed the "doi-access=free" since I can confirm (I've tried on my phone via SFR in France). — Vincent Lefèvre (talk) 14:58, 13 November 2023 (UTC)[reply]

Thank you! My bad, I did that while connected to an IP that had the article available, but didn't notice... I'm going to review a number of other occurrences of that problem. TheMathCat (talk) 17:27, 13 November 2023 (UTC)[reply]

Undefined operations

What are the circle-plus and circle-minus operations used in the algorithm? 120.16.52.10 (talk) 05:16, 12 December 2023 (UTC)[reply]

I've just clarified. — Vincent Lefèvre (talk) 11:51, 12 December 2023 (UTC)[reply]
