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