| Begin |
| Initialization. Set the generation counter ; initialize the population of krill individuals randomly and each |
| krill corresponds to a potential solution to the given problem; set the foraging speed , maximum diffusion |
| speed , and maximum induced speed ; |
| Fitness evaluation. Evaluate each krill individual according to its position. |
| While the termination criterion is not satisfied or Generation do |
| Sort the population krill from best to worst. |
| for (all krill) do |
| Perform the following motion calculation. |
| Motion induced by the presence of other individuals |
| Foraging motion |
| Physical diffusion |
| Implement the genetic operators. |
| Update the krill individual position in the search space. |
| Evaluate each krill individual according to its new position. |
| end for |
| Sort the population krill from best to worst and find the current best. |
| . |
| End While |
| Post-processing the results and visualization. |
