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 allocation optimization algorithm" » "modified allocation optimization algorithms", "modified allocation optimisation algorithm", "modified allocation estimation algorithm", "modified location optimization algorithm"

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