Perhaps you should try some spelling variations:
"modified adam approximation algorithm" » "modified _ approximation algorithm", "modified time approximation algorithm", "modified average approximation algorithm", "modified df approximation algorithm", "modified near approximation algorithm"
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca 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 adam approximation algorithm") or ("modified one approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adam approximation algorithm") OR ("modified one approximation algorithms")).
• Removing quotes may allow a broader search: (( modified adam approximation algorithm ) or ( modified one approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adam approximation algorithm") or ("modified one approximation algorithms"))*.
