Solution

The correct answer is (C), (D), (A), (B)

EXPLANATION:

• Permutation Encoding (C):
  • In this encoding strategy, the representation of solutions is done by permuting the order of elements in the solution space. This is useful when the order or arrangement of elements matters.
• Gray Coding (D):
  • Gray coding is a binary numeral system where two successive values differ in only one bit. In the context of genetic algorithms, Gray coding is used to reduce the chance of introducing errors during the encoding and decoding processes.
• Binary Encoding (A):
  • Binary encoding is the most basic form of encoding where each parameter of a solution is represented as a string of binary digits (0s and 1s). It's a common and simple way to represent solutions in genetic algorithms.
• Real-valued Encoding (B):
  • Real-valued encoding is used when the parameters of the solution space are continuous. In this encoding, real numbers are used to represent the values of parameters. It allows for a more fine-grained representation of solutions in cases where the solution space is continuous.

So, the correct sequence is (C), (D), (A), (B), as given in option 3) (C), (D), (A), (B).
