Modified Atom Search Optimization Based on Immunologic Mechanism and Reinforcement Learning

Algorithm 1

Pseudocode of the atom search optimization algorithm.

(1)	Randomly initialize a set of atoms X (solutions) and their velocity , and .
(2)	While the stop criterion is not satisfied do
(3)	For each atom do
(4)	Calculate the fitness value Fit;
(5)	If then
(6)	;
(7)	;
(8)	End If.
(9)	Calculate the massing using equations (2) and (3);
(10)	Determine its K neighbors using equation (4);
(11)	Calculate the interaction force and the constraint force using equations (11) and (12), respectively;
(12)	Calculate the acceleration using equation (14);
(13)	Update the velocity using equation (15);
(14)	Update the position using equation (16);
(15)	End For.
(16)	End While.
(17)	Find the best solution so far
