Perhaps you should try some spelling variations:
"modified network approximation algorithm" » "modified network approximation algorithms", "certified network approximation algorithm", "defined network approximation algorithm", "modified near approximation algorithm"
"modified based predation algorithm" » "modified based predators algorithm", "modified based estimation algorithm", "modified based prediction algorithm", "modified based gradation algorithm", "modified male 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 based predation algorithm") or ("modified network approximation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified based predation algorithm") OR ("modified network approximation algorithm")).
• Removing quotes may allow a broader search: (( modified based predation algorithm ) or ( modified network approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified based predation algorithm") or ("modified network approximation algorithm"))*.
