Perhaps you should try some spelling variations:
"modified dfverage approximation algorithms" » "modified average approximation algorithms", "modified _verage approximation algorithms", "modified adamverage approximation algorithms", "modified bi1verage approximation algorithms"
"modified df solution algorithms" » "modified df solution algorithm", "modified df evolution algorithm", "modified df convolution algorithms", "modified _ solution algorithms", "modified adam solution algorithms", "modified bi1 solution algorithms", "modified drug solution algorithms", "modified up solutions 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 solution algorithms") or ("modified dfverage approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df solution algorithms") OR ("modified dfverage approximation algorithms")).
• Removing quotes may allow a broader search: (( modified df solution algorithms ) or ( modified dfverage approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified df solution algorithms") or ("modified dfverage approximation algorithms"))*.
