Abstract

The authors give an online algorithm for computing a canonical signed digit representation of minimal Hamming weight for any integer n. Using combinatorial techniques, the probability distributions Pr(K/sub r/=h), where K/sub r/ is taken to be a random variable on the uniform probability space of k-digit integers is computed. Also, using a Markov chain analysis, it is shown that E(K/sub r/) approximately (r-1)k/(r+1) as k to infinity.
