Perhaps you should try some spelling variations:
"modified quadratic estimation algorithms" » "modified quadratic estimation algorithm", "modified quadratic optimization algorithms", "modified quadratic optimisation algorithm", "modified quantile estimation algorithms"
"modified notion optimized algorithms" » "modified notion optimized algorithm", "modified notion optimizer algorithms", "modified notion 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 optimized algorithms") OR ("modified quadratic estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified notion optimized algorithms\") OR (\"modified quadratic estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified notion optimized algorithms ) OR ( modified quadratic estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimized algorithms") OR ("modified quadratic estimation algorithms"))*.
