Perhaps you should try some spelling variations:
"modified time approximation algorithms" » "modified one approximation algorithms", "modified _ approximation algorithms", "modified bi1 approximation algorithms", "modified male approximation algorithms"
"modified learning data algorithm" » "mobile learning data algorithm", "modified caging data algorithm", "modified learning adam algorithm", "modified learning a algorithm", "modified learning due algorithm", "modified learning via algorithm"

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 data algorithm") OR ("modified time approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified learning data algorithm\") OR (\"modified time approximation algorithms\"))".
• Removing quotes may allow a broader search: (( modified learning data algorithm ) OR ( modified time approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified learning data algorithm") OR ("modified time approximation algorithms"))*.
