Perhaps you should try some spelling variations:
"modified learning aided algorithm" » "mobile learning aided algorithm", "modified caging aided algorithm", "modified learning adam algorithm", "modified learning driven algorithm", "modified learning winner algorithm", "modified learning based algorithm", "modified learning model algorithm"
"modified network approximation algorithms" » "certified network approximation algorithms", "defined network approximation algorithms", "modified near 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 learning aided algorithm\") OR (\"modified network approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified learning aided algorithm ) OR ( modified network approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning aided algorithm") OR ("modified network approximation algorithms"))*.
