Perhaps you should try some spelling variations:
"modified learning source algorithm" » "mobile learning source algorithm", "modified caging source algorithm", "modified learning our algorithm", "modified learning search algorithm", "modified learning journey 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 learning source algorithm") OR ("modified one approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified learning source algorithm\") OR (\"modified one approximation algorithms\"))".
• Removing quotes may allow a broader search: (( modified learning source algorithm ) OR ( modified one approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified learning source algorithm") OR ("modified one approximation algorithms"))*.
