One question of understanding: Does "Manifold" in the name of the site is meant in the sense of "Riemannian Manifold"? (RM has a fixed - positive - meaning in the math community.)

@KeGuThueringer I do not know the origin of this platform’s name

Is it allowed to bet here and at the same time to secretly solve lots of open Erdos problems - and decide near the end of the year how many of these solutions to disclose? To be open: The intention is to improve my betting chances here.

@KeGuThueringer yes

Does an existing solution found by AI literature review count as "solved during 2026"?

@ZongshuWu The market will be resolved by the difference between the N in “N have been solved” as stated on the website at the end of the year and 451. Right now, the website says “475 (41%) have been solved” so the difference today is 24.

@BraydonDymm I take that as a "yes" to my question

Make sure you do not measure this by how the "total solved" changes, since this will include old solutions also. You have to manually count which of those solutions happened during 2026.

@ThomaslZZ0 The market will be resolved by the difference between the N in “N have been solved” as stated on the website at the end of the year and 451. Right now, the website says “466 (41%) have been solved” so the difference today is 15.

@BraydonDymm You should reword "solved by the end of 2026" as "solved during 2026". And you may want to specify a timezone.

@vee updated

On 1 January 2025 there were 292 solved out of 895 total

@duck_master I’m using the website as the official source. Do you have a different official source?

@BraydonDymm That website is fantastic. However, the statistics it keeps, is unreliable. - old-bielefelder on erdosproblems.com

@KeGuThueringer the link you shared is the same one I’m using above. I’m not aware of any more reliable statistics.
