Perhaps you should try some spelling variations:
"modified aware protection algorithm" » "modified aware predation algorithm", "modified aware evolution algorithm", "modified aware solution algorithm", "modified mark protection algorithm", "modified adam protection algorithm", "modified male protection algorithm", "modified near protection algorithm"
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified aware protection algorithm\") OR (\"modified notion approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified aware protection algorithm ) OR ( modified notion approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified aware protection algorithm") OR ("modified notion approximation algorithms"))*.
