An Enhanced Ant Colony Optimization Mechanism for the Classification of Depressive Disorders

Algorithm 1

ACO algorithm.

	Initialize ACO
	Repeat
	Set the parameters of heuristics as and
	For ant
	Select a set of features utilizing rule of probabilistic
	Measure the value of fitness
	Update the limited pheromone
	End for
	Assess the solutions produced by all the ants in a tour
	choose the tour’s greatest and worst performers.
	Update the pheromone globally
	The rate of evaporation reduces pheromone intensity
	If after the tour a shorter route is discovered
	Update the parameter of heuristics and
	End if
	Until the criteria for stopping are met
	Choose the attributes that have the greatest pheromone levels
