In order to count the number of n -variable balanced rotation symmetric Boolean functions, N n, we divide the 2 n elements of ( GF ( 2)) n into two groups A n and B n of equal size 2 n − 1. Since the function that we are considering is rotation symmetric, the vectors in the same orbit must be in the same group. maple ridge business awardsWebAn algorithm for the design of rotation-symmetric functions is given and two classes of functions are examined. These classes are important from a practical point of view as their forms are short. We show that shortening of rotation-symmetric functions paradoxically leads to more expensive evaluation process. maple ridge business license application
