Perhaps you should try some spelling variations:
"modified network approximation algorithms" » "certified network approximation algorithms", "defined network approximation algorithms", "modified near approximation algorithms"
"machine learning aided algorithm" » "machine learning adam algorithm", "machine learning driven algorithm", "machine learning winner algorithm", "machine learning based algorithm", "machine learning model algorithm"

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

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