plain-language theorem explainer

The declaration shows that under the named hypothesis for parameter n, every ProgramTarget of size n admits a map from CNF formulas to optional assignments that returns a satisfying assignment exactly when one exists. Complexity researchers working on SAT decision procedures inside the Recognition Science model would cite this when establishing efficient solvability. The proof is a direct one-line application of the hypothesis with no additional steps.

Claim. Assuming the hypothesis that a polynomial-time 3SAT algorithm exists for $n$ variables, for any program target of size $n$ there exists a function $alg$ from CNF formulas over $n$ variables to optional assignments such that $alg$ returns a satisfying assignment for every satisfiable formula and returns none for every unsatisfiable formula.

background

The module constructs fully-determined backpropagation states from total assignments. CNF formulas are structures consisting of lists of clauses over $n$ variables, with evaluation defined by checking that every clause holds under a given assignment. Satisfiability is the existence of at least one assignment making the entire conjunction true. Upstream results supply the cellular-automaton step operation that applies a local rule to each cell and the basic definition of an assignment as a map from variables to booleans.

proof idea

The proof is a one-line wrapper that applies the hypothesis polynomial_time_3sat_algorithm_hypothesis directly to the given ProgramTarget.

why it matters

The result supplies the existence claim for a polynomial-time 3SAT solver that the SAT completeness module requires. It closes the semantic existence argument for backpropagation under unique XOR solutions without depending on a concrete cellular-automaton step system. No downstream theorems are recorded, indicating the declaration functions as a terminal interface for the polynomial-time claim in the complexity domain.
