Short-Term Wind Speed Forecasting Based on Ensemble Online Sequential Extreme Learning Machine and Bayesian Optimization

Algorithm 1

The bat algorithm.

	Bat Algorithm (f)
	Input: Target function
	Initialize the bat population with the velocity , the pulse frequency ,
	the pulse rates and the loudness , .
	For each bat , do
	Employ equations (5)–(7) to produce new solutions.
	If , then
	Choose one candidate solution from the optimal solutions.
	If and , then
	Accept the newly proposed solutions.
	Update and by equations (8) and (9).
	Return the current best .
