Perhaps you should try some spelling variations:
"modified parameter optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified caging predation algorithm") or ("modified parameter optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified caging predation algorithm") OR ("modified parameter optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified caging predation algorithm ) or ( modified parameter optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified caging predation algorithm") or ("modified parameter optimisation algorithm"))*.
