Perhaps you should try some spelling variations:
"modified based predation algorithm" » "modified based predators algorithm", "modified based estimation algorithm", "modified based prediction algorithm", "modified based gradation algorithm", "modified male predation algorithm"
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca approximation algorithms"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified based predation algorithm") OR ("modified one approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified based predation algorithm ) or ( modified one approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified based predation algorithm") or ("modified one approximation algorithms"))*.
