Perhaps you should try some spelling variations:
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"
"modified nacl evolution algorithm" » "modified nacl solution algorithm", "modified nacl evolutionary algorithm", "modified nacl convolution algorithms", "modified early evolution algorithm", "modified co evolution algorithm", "modified male evolution algorithm", "modified near evolution algorithm", "modified orca evolution algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified nacl evolution algorithm") OR ("modified notion estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified nacl evolution algorithm\") OR (\"modified notion estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified nacl evolution algorithm ) OR ( modified notion estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified nacl evolution algorithm") OR ("modified notion estimation algorithms"))*.
