[Retracted] Atom Search Optimization with the Deep Transfer Learning-Driven Esophageal Cancer Classification Model

Algorithm 1

Pseudocode of ASO algorithm.

	Begin
	Initialize population in searching area
	While termination condition is unsatisfied do
	Determine fitness of every atom;
	Determine atom mass;
	Compute Kbest neighbor;
	Determine interaction and constrain forces
	Compute acceleration;
	Upgrade velocity;
	Upgrade position.
	End while
