Root Growth Optimizer with Self-Similar Propagation

Pseudocode 1

Pseudocode of RGO.
(1)Initialize the positions of root apices
(2)Calculate the fitness values of each root apex
(3)While not meet the terminal condition
(4) Divide all the root apices into main roots, lateral roots and aging roots
(5) For each main root apex
   Regrow with the root regrowing operator
   Branch with the root branching operator
   Evaluate the fitness value of new root apices
   Implement inhibition mechanism of plant hormones
   End for
(6) For each lateral root apex
   Produce a new apex replacing the original one
   End for
(7) Implement shrinkage operator
(8) Rank root apices and label elite roots
(9)End while
(10) Postprocess results
