The 9 pages that link to Polynomial time, each with the reason it gives.
P versus NP problemRelated: Polynomial time defines efficiency for both solving and verification.
Time complexityRelated: Polynomial growth is a central benchmark for tractable computation.
Cook–Levin theoremRelated: Both the reduction and the verification fit this resource bound.
NP-hardnessRelated: The defining reductions must be computable within this time bound.
Hartmanis–Stearns conjectureNarrower topic: It defines the efficiency threshold shared by P and NP.
