UnverifiedThe tempering process of the Mersenne Twister algorithm consists of four steps: a right shift of 11 bits, a left shift of 7 bits combined with a mask, a left shift of 15 bits combined with a mask, and a right shift of 18 bits.65% similarUnverifiedIn certain scenarios (such as special combinations of modulo operations), manual optimization can still outperform the compiler's automatic constant-division conversion.60% similar
