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 changing optimized algorithms" » "modified changing optimized algorithm", "modified changing optimizer algorithms", "modified changing optimization algorithms", "modified choosing optimizer algorithms", "modified caging optimized 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 changing optimized algorithms") OR ("modified notion estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified changing optimized algorithms\") OR (\"modified notion estimation algorithms\"))*".
• Removing quotes may allow a broader search: (( modified changing optimized algorithms ) OR ( modified notion estimation algorithms ))*.
