Perhaps you should try some spelling variations:
"modified near approximation algorithms" » "modified one approximation algorithms", "modified network approximation algorithms", "modified _ approximation algorithms", "modified seird approximation algorithms", "modified adam approximation algorithms"
"model using method algorithm" » "model using mom algorithm", "model nursing methods algorithm", "model focusing method algorithm", "model using metal algorithm", "code using method algorithm", "models nursing method algorithm", "powder using method algorithm"

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: "((\"model using method algorithm\") OR (\"modified near approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( model using method algorithm ) OR ( modified near approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("model using method algorithm") OR ("modified near approximation algorithms"))*.
