Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"
"modified caging predation algorithm" » "modified caging predators algorithm", "modified caging estimation algorithm", "modified aging predation algorithm", "modified changing predation algorithm", "modified charging predation algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified caging predation algorithm\") OR (\"modified allocation optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified caging predation algorithm ) OR ( modified allocation optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified caging predation algorithm") OR ("modified allocation optimisation algorithm"))*.
