What is recorded here?
Presented shorter three-value sorting routines and hardware-specific speed comparisons, exposing the importance of the permitted program space and benchmark setup.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The 14-instruction routine uses a loop. The repository erratum restricts the 15-instruction branchless routine to non-negative inputs; it is not a signed-input replacement as originally presented. These do not establish optimality within AlphaDev’s exact search grammar or a universal speed advantage. Neri explicitly makes no originality claim for the straightforward faster routine. Later Kauer code is separately credited. WRS read sources without compiling them or reproducing timings.
