WebA proposed real coded genetic algorithm based radial basis function neural network classifier is employed to perform effective classification of healthy and cancer affected lung images. Real Coded Genetic Algorithm (RCGA) is proposed to overcome the Hamming Cliff problem encountered with the Binary Coded Genetic Algorithm (BCGA). WebNB. Hamming cliffs (where you have to flip more than one bit to reach the nearest neighbor) further make binary search difficult. Using Gray coding helps. NB. With real valued …

"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, " - Hamming cliff problem
