Sequences of subrandom numbers can be generated from random numbers by imposing a negative correlation on those random numbers. One way to do this is to start with a set of random numbers r i {\displaystyle r_{i}} on [ 0 , 0.5 ) {\displaystyle [0,0.5)} and construct subrandom numbers s i {\displaystyle s_{i}} which are uniform on [ 0 , 1 ) {\displaystyle [0,1)} using:
