Dragonfly Algorithm and Its Applications in Applied Science Survey

Visual 1

Pseudocode for DA [9].

	Initialize the dragonflies population Xi (i = 1, 2, …, n)
	Initialize step vectors Xi (i = 1, 2, …, n)
	while the end condition is not satisfied
	Calculate the objective values of all dragonflies
	Update the food source and enemy
	Update , s, a, c, f, and e
	Calculate S, A, C, F, and E using equations (1)–(5)
	Update neighbouring radius
	If a dragonfly has at least one neighbouring dragonfly
	Update velocity vector using equation (6)
	Update position vector using equation (7)
	Else
	Update the position vector using Lévy flight
	End if
	Check and correct the new positions based on the
	boundaries of variables
	End while
