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 water solution algorithms" » "modified water solution algorithm", "modified water evolution algorithm", "modified water convolution algorithms", "modified male solution algorithms", "modified water absorption algorithms"

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

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