As defined here, one-way functions are defined so they are polynomial time, but their inverse is not. However, the same concept could be thought of more generally as functions with a strict upper bound that is a lower bound on their inverse. Is there any information about this more general problem, how it is formulated and described, it’s implications, and whether or not it has been solved?
 
== Half probability that prime is even? ==
 
In the section Candidates for one way functions, it is stated "...because the probability that an arbitrary p is odd is 1/2, and likewise for q(...)". But since 2 is the only even prime, that seems not correct? [[Special:Contributions/89.99.34.48|89.99.34.48]] ([[User talk:89.99.34.48|talk]]) 07:11, 24 July 2022 (UTC)
