Perhaps you should try some spelling variations:
"modified elements convolution algorithms" » "modified elements evolution algorithm", "modified elements solution 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 one approximation algorithms") or ("modified elements convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified one approximation algorithms") OR ("modified elements convolution algorithms")).
• Removing quotes may allow a broader search: (( modified one approximation algorithms ) or ( modified elements convolution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified one approximation algorithms") or ("modified elements convolution algorithms"))*.
