Line 192: For a black-box problem, the implementation inside the black box should not matter. Computationally speaking, the function could just as well be implemented mechanically, using wooden gears, as long as it maps each input to a unique output. Using the same reasoning, I could design a classical setup where one of two computers is equipped with an X-ray camera and then define the problem such that the black box must not contain lead shielding—giving the X-ray-equipped computer an unfair advantage. Shouldn't the concept of an algorithm be independent of such physically constrained advantages? <!-- Template:Unsigned IP --><small class="autosigned">— Preceding [[Wikipedia:Signatures\|unsigned]] comment added by [[Special:Contributions/2001:1C06:2704:D500:DF17:1D45:B3B2:2107\|2001:1C06:2704:D500:DF17:1D45:B3B2:2107]] ([[User talk:2001:1C06:2704:D500:DF17:1D45:B3B2:2107#top\|talk]]) 12:37, 7 March 2025 (UTC)</small> <!--Autosigned by SineBot-->
