Perhaps you should try some spelling variations:
"modified near convolution algorithms" » "modified near evolution algorithm", "modified near solution algorithm", "modified learning convolution algorithms", "modified seird convolution algorithms", "modified adam convolution algorithms"
"modified coverage approximation algorithms" » "modified average 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 near convolution algorithms") or ("modified coverage approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified near convolution algorithms") OR ("modified coverage approximation algorithms"))*.
• Removing quotes may allow a broader search: (( modified near convolution algorithms ) or ( modified coverage approximation algorithms ))*.
