So IIUC (10,10) is better than (5,5), (10,22), and the originally proposed (14,22)? Then should I make a change to make all 4 costs (SF, DF, SI, DI) 10? I'd still want DI % 1000000007 to be reduced as reciprocal sequence (but not SI % 1000000007) since DI % (smaller const) is quite important for some workloads like competitive programming. However "adapting with different modulos" is not possible w/o refactoring generic code so it must be deferred to at least GCC 15. -- Xi Ruoyao <xry...@xry111.site> School of Aerospace Science and Technology, Xidian University
