    It is not the case that The Cobham-Edmonds Thesis conflates mathematical tractability with physical feasibility by ignoring the magnitude of polynomial constants and exponents.

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.The thesis distinguishes feasibility classes precisely because polynomial-time algorithms typically have reasonable constants in practice.
      ?

      Think about whether this reason is strong or weak

    • 2.Exponential algorithms are uniformly worse across problem instances; polynomial algorithms scale differently, making the distinction meaningful.
      ?

      Think about whether this reason is strong or weak

    • 3.Criticizing P for ignoring constants conflates descriptive theory with prescriptive engineering—they serve different purposes.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.A polynomial algorithm with exponent 100 is computationally infeasible despite being 'tractable' by complexity theory standards.
      ?

      Think about whether this reason is strong or weak

    • 2.Physical constraints (time, energy, hardware limits) depend on actual constants, not just asymptotic behavior as n→∞.
      ?

      Think about whether this reason is strong or weak

    • 3.Complexity classes conflate theoretical computability with practical solvability, misleading resource allocation in engineering.
      ?

      Think about whether this reason is strong or weak
