Let the population of chromosomes in genetic algorithm is represented in terms of binary number. The strength of fitness of a chromosome x in decimal form, , is given by f(x) Sf(x) = where f(x) = x2 Σf(x) P The population is given by where: P = {(01101, (11000), (01000), (10011)} The strength of fitness of chromosome (11000) is -------------

1. A24
2. B576
3. C14.4
4. D49.2

Show answer & explanation

Correct answer: D. 49.2

Explanation

x values 13, 24, 8, 19 give x² = 169, 576, 64, 361 (sum 1170). Strength of 11000 = 576/1170 ≈ 49.2%.
