>>107163414 (OP)
A constructive proof that P = NP would be revolutionary in the computer science world, especially for cryptography. Public key cryptosystems like HTTPS and OpenPGP would become crackable overnight.
A proof that P != NP would just be like "oh cool, we already thought that but it's nice to have confirmation". Wouldn't change anything really.
>>107164823 >The big oh constant
The absolute state of /g/ in 2025. Big O notation ignores constant multipliers, O(2x) is exact same set as O(x).
You are correct that a constructive proof that P = NP would not necessarily lead to NP-complete problems being solvable. The polynomial may have such a high degree that it is practically unfeasible.
