Hamming cliff problem
WebHigher dimension ver- sions are easily constructed by summing n copies of a 1-dimensional version: Experiments such as these suggest that switching to Gray coding can improve … Webso-called Hamming Cliff problem. The Hamming distance indicates the number of bits that are different between two binary strings. In a Hamming Cliff situation, a very large perturbation in binary space would cause only a small change in integer space. For example, the decoded value of the binary string 01 111 111 is 127 in the integer space,
