Perhaps you should try some spelling variations:
"modified adaptive optimisation algorithm" » "modified adaptive optimization algorithms", "modified adaptive estimation algorithm", "modified adaptive estimation algorithms", "modified passive optimisation algorithm"
"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 adaptive optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified caging predation algorithm") OR ("modified adaptive optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified caging predation algorithm ) or ( modified adaptive optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified caging predation algorithm") or ("modified adaptive optimisation algorithm"))*.
