Pseudocode 8

Pseudocode of the mut function.

population  mut(chrom, 𝑝_𝑚)

Input: chrom indicates a chromosome in the population;

       𝑝_𝑚 indicates the probability of mutation.

Output: chrom2 indicates a chromosome after mutatation.

 chrom2 ← chrom;

 for  the 𝑗th gene ∈ chrom

  𝑟 ← generate a random;

  if  𝑟 < 𝑝_𝑚

   gene ← ∀  𝑡∈{0,1,2}∧𝑡≠ gene;

   chrom2(𝑗) ← gene;

  end if

 end for

 Return  chrom2;
