[Retracted] Design of a Regional Economic Forecasting Model Using Optimal Nonlinear Support Vector Machines

Algorithm 1

  Pseudocode of the CSO algorithm.

	Begin.
	Objective functions of f(x), x = (x1, x2, …, xd)T
	Populations initialization of host nests xi,
	While (t < Maximum_iteration) or (termination condition)
	Get a cuckoo arbitrarily via Lévy flight
	Determine the qualities/fitness as Fi
	Select nest amongst (n, j) arbitrarily
	If (Fi ≥ Fj),
	Substitute j in newly attained solution;
	End
	An fraction (pa), poor nests are discarded and new one is derived;
	Retain optimal solution, (with quality solution);
	Sort the solutions and determine current best
	End
	Postprocess and visualize results
	End
