摘要
A string ... a2a1a0 over the alphabet {–1,0,1} is said to be a minimal signed-binary representation of an integer n if n = ∑k≥0ak2k and the number of non-zero digits is minimal. We present a loopless (and hence a Gray code) algorithm for generating all minimal signed binary representations of a given integer n.
