Perhaps you should try some spelling variations:
"modified model predation algorithm" » "modified model predators algorithm", "modified model estimation algorithm", "modified model reduction algorithm", "modified model predictive algorithm", "modified model predicting algorithm", "modified male predation algorithm"
"modified average approximation algorithms" » "modified coverage approximation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified average approximation algorithms") OR ("modified model predation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified average approximation algorithms\") OR (\"modified model predation algorithm\"))".
• Removing quotes may allow a broader search: (( modified average approximation algorithms ) OR ( modified model predation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified average approximation algorithms") OR ("modified model predation algorithm"))*.
