Perhaps you should try some spelling variations:
"modified objective predation algorithm" » "modified objective allocation algorithm", "modified objective predators algorithm", "modified objective estimation algorithm"
"modified a approximation algorithms" » "modified _ approximation algorithms", "modified one approximation algorithms", "modified time approximation algorithms", "modified df approximation algorithms", "modified adam 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 a approximation algorithms") OR ("modified objective predation algorithm"))~.
• Removing quotes may allow a broader search: (( modified a approximation algorithms ) or ( modified objective predation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified a approximation algorithms") or ("modified objective predation algorithm"))*.
