Perhaps you should try some spelling variations:
"nacl convolution algorithms" » "nacl evolution algorithm", "nacl solution algorithm", "nacl solution algorithms"
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"_ simulation algorithm" » "_ estimation algorithm", "_ solution algorithm", "_ estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("nacl convolution algorithms") or ("_ simulation algorithm"))) or ("_ optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("nacl convolution algorithms") OR ("_ simulation algorithm"))) OR ("_ optimisation algorithm")).
• Removing quotes may allow a broader search: (((( nacl convolution algorithms ) or ( _ simulation algorithm ))) or ( _ optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("nacl convolution algorithms") or ("_ simulation algorithm"))) or ("_ optimisation algorithm"))*.
