Perhaps you should try some spelling variations:
"modified _mplexity approximation algorithms" » "modified complexity approximation algorithms"
"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"

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 _mplexity approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified nacl convolution algorithms ) or ( modified _mplexity approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified nacl convolution algorithms") or ("modified _mplexity approximation algorithms"))*.
