Hamming cliff problem
WebSuch Hamming cliffs present a problem for the algorithm, as both mutation and crossover can not overcome them easily. It is desirable that the encoding makes the representation as robust as possible. This means that even if a piece of the representation is randomly changed, it will still represent a viable individual. WebHowever, the coding of real-valued variables in finite-length strings causes a number of difficulties: inability to achieve arbitrary precision in the obtained solution, fixed mapping of problem variables, inherent Hamming cliff problem associated with binary coding, and processing of Holland's schemata in continuous search space.
