RNG(Random Number Generator)

• 기욱팀장이 작성예정• 32bit RNG

• Polynomial can be modified

• Default polynomial: F(x) = x31 + x30 + x29 + x9 + x

pseudo-random number처음에 주어지는 초깃값을 이용하여 이미 결정되어 있는 메커니즘(의사 난수 생성기)에 의해 생성되는 수. 난수는 생성방법이 결정되어 있지 않으며, 다음에 생성될 값을 전혀 예측할 수 없으나 의사 난수 생성기에 의해 생성되는 수는 초깃값을 알면 계산될 수도 있으므로 진짜 난수와 구별하여 의사난수라 부른다. [네이버 지식백과]
