Perhaps you should try some spelling variations:
"modified df evaluation algorithms" » "modified df evolution algorithm", "modified df estimation algorithms", "modified df convolution algorithms", "modified _ evaluation algorithms", "modified a valuation algorithms", "modified study evaluation algorithms", "modified adam evaluation algorithms", "modified bi1 evaluation algorithms"
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one 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 df evaluation algorithms") OR ("modified notion approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified df evaluation algorithms\") OR (\"modified notion approximation algorithms\"))".
• Removing quotes may allow a broader search: (( modified df evaluation algorithms ) OR ( modified notion approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified df evaluation algorithms") OR ("modified notion approximation algorithms"))*.
