A New Dual-Mode GEP Prediction Algorithm Based on Irregularity and Similar Period

Algorithm 2

SPM.

	Begin:
	Step1:Data preprocessing
(1)	For i = 1 to G-L do//base array
(2)
(3)	End for;
(4)	For j = 1 to W do//subgoal modeling and forecast sets
(5)	Datas [j] ← Y_datas [j]...Y_datas [j + (N-3) L];
(6)	End for;
(7)	Com_Chromosme [W] ← structure container for complex subgoals;
	Step2:genetic evolution process
(8)	For t = 1 to W do
(9)	CHROMOSME [ ] ← stochastic original population using Datas [t];
(10)	BEST ← Using IPM algorithm get the best individual;
(11)	Com_Chromosme [t] ← BEST
(12)	End for;
(13)	Return Com_Chromosme [W] as result;
	Step3:use compound target
(14)	For x = 1 to P do
(15)	FORECAST gets using Com_Chromosme [x mod L];
(16)	SUM_ERROR += gets calculate the error;
(17)	End for;
(18)	AVE_ERROR gets SUM_ERROR/P;
	End;
