GIS-Based Niche Hybrid Bat Algorithm for Solving Optimal Spatial Search

Algorithm 1

The pseudocode of the original BA.

	Objective function F(x), x = (x1,x2,...,xd)^T
	Initialize the bat population xi (i = 1,2, …, n) and
	Define the pulse frequency fi at xi
	Initialize the pulse rates ri and the loudness Ai
	While (t < Imax) (where Imax is the max number of iterations)
	Generate new solutions by adjusting the frequency, and updating velocities and locations using equations (1)–(3)
	If (rand1 > ri)
	Select a solution among the best solutions
	Generate a local solution around the selected best solution using equation (4)
	End if
	Generate a new solution by flying randomly
	If (rand2 < Ai and f(xi) < f(xgbest))
	Accept the new solutions
	Increase ri and reduce Ai using equations (5) and (6)
	End if
	Rank the bats and find the current best xgbest
	End while
