Algorithm 1

Pseudocode of KHA.
Begin
Parameter initiation: generation counter G, population P, , , and .
Compute fitness of all krills based on the starting location.
While do
 Arrange the individuals with respect to fitness.
 for i = 1: NP (every krill) do
  Carry out motion computation
  Foraging movement
  Physical diffusion
 Derive the genetic operators.
 Upgrade location of krills in the searching areas in the search space.
 Determine fitness of all krills with respect to krill location.
