Constructing a truth table requires explicit enumeration of 2^n rows, while a P=NP SAT algorithm need not enumerate valuations, making 'no harder than' equivocate on distinct complexity notions.

Reasons For

1 perspective

Reason for

1.Truth tables require worst-case 2^n explicit row construction; P=NP SAT solvers could use shortcuts like unit propagation, avoiding full enumeration.
?
Think about whether this reason is strong or weak
2.Worst-case and average-case complexity differ fundamentally; 'no harder than' conflates explicit construction time with decision time.
?
Think about whether this reason is strong or weak
3.A polynomial SAT algorithm wouldn't need to output all valuations, only verify satisfiability, reducing information-theoretic requirements.
?
Think about whether this reason is strong or weak

Reasons Against

1 perspective

Reason against

1.Both truth tables and P=NP SAT algorithms ultimately depend on evaluating formulas under valuations; the underlying hardness is identical.
?
Think about whether this reason is strong or weak
2.Any algorithm deciding SAT on n variables must implicitly distinguish between 2^n cases; avoiding explicit enumeration doesn't eliminate the work.
?
Think about whether this reason is strong or weak
3.Complexity theory measures computational operations, not data representation; whether output is 'enumerated' or 'implicit' is philosophically distinct from algorithmic hardness.
?
Think about whether this reason is strong or weak

Key Terms

2^n rows(as used in mathematics and logic): A mathematical expression meaning the number of rows doubles with each new variable (2 to the power of n), so 3 variables would need 2³=8 rows, 4 variables would need 16 rows, and so on.
Equivocate(in describing the logical flaw Arnauld identified): To use a word or phrase in two different ways within an argument, making the reasoning unclear or misleading.
P=NP(mathematics and computer science): A famous unsolved question in computer science asking whether two classes of problems (P and NP) are actually the same—if true, it would mean certain very hard problems can actually be solved quickly.
SAT algorithm(as used in computer science): A computer method for solving 'satisfiability' problems, which ask whether you can find values that make a logical statement true.
complexity notions(as used in computer science): Different ways of measuring how hard or easy a computational problem is to solve (like time needed, space needed, or types of approaches allowed).
enumeration(Referred to as 'enumeration2' — the reductive/analytical use of enumeration in Cartesian method, distinct from simple listing): A methodological operation that reduces a complex problem to an ordered series of simpler component problems
truth table(as used in logic): A chart that lists every possible combination of true/false values for a logical statement and shows what the result is in each case.
valuations(as used in logic): The assignment of true or false values to each variable in a logical statement.
