Algorithm 2

Mutation operation.

	I ⟵ An individual
	Np ⟵ Number of potential hub locations
	O ⟵ Set of the locations of genes in I with the code of one
	Z ⟵ Set of the locations of genes in I with the code of zero
	no ⟵ Number of ones in I
	nz ⟵ Number of zeros in I
	n ⟵ min (no, nz)
	for k ⟵ 1 to n
	Change the codes of the genes (I(O(k)), I(Z(k))) with probability Pm
	end if
