Perhaps you should try some spelling variations:
"modified nacl convolution algorithms" » "modified nacl evolution algorithm", "modified nacl solution algorithm", "modified nacl solution algorithms", "modified male convolution algorithms", "modified near convolution algorithms", "modified orca convolution algorithms"
"modified average approximation algorithms" » "modified coverage approximation algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified nacl convolution algorithms") OR ("modified average approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified nacl convolution algorithms ) or ( modified average approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified nacl convolution algorithms") or ("modified average approximation algorithms"))*.
