Novel Crow Swarm Optimization Algorithm and Selection Approach for Optimal Deep Learning COVID-19 Diagnostic Model

Algorithm 1

Pseudocode for the selection approach for optimal deep learning COVID-19 diagnostic model based on novel CSO algorithm.

	Input: Read CT Lung images with length of H x W
	Begin
	Data preprocessing
	Feature selection of CNN
	While (I ≤ max.epoch)
	Deep learning models
	Evaluation of deep learning methods
	While (j < max. iteration)
	CSO mathematical model and algorithm
	Group Division
	Update speed by E.q (7).
	Update position by E.q (8)
	Update angle bt E.q (9)
	End while
	Multiple weight with corresponding criteria
	Selection best model based on highest final results
	Return: Ranking of COVID-19 diagnosis models
	Output: Best COVID-19 diagnosis models
	End
