A Selective Biogeography-Based Optimizer Considering Resource Allocation for Large-Scale Global Optimization

Algorithm 4

Pseudocodes of CC_SBBO_RA. Therein, f is an objective function; D is the number of subcomponents.

(1)	Divide f into D exclusive subcomponents according to RDG [18];
(2)	Initial imp_best = 0;
(3)	Initial RFI = zeros (D, 1);
(4)	If imp_best ≤ ξ (ξ is a threshold value), do
(5)	For i = 1: D, do
(6)	Evolve subgroup i by Algorithm 2;
(7)	Update RFI based on equation (7);
(8)	End for
(9)	Else
(10)	Allocate computing resource to the subgroup l and evolve it according to Algorithm 3;
(11)	End if
(12)	Stop if halting criteria are satisfied; otherwise go to If for the next evolution.
