What is recorded here?
Encoded polynomial-time nondeterministic computations as satisfiability instances and established a completeness result using the paper’s definition of P-reducibility.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The original defines query-machine P-reducibility and states its theorem using DNF tautologies. Modern reduction notation must not be silently substituted. This record covers Cook’s paper without exhausting Levin’s independent work; it does not settle P versus NP.
